Hi,
I am unable to reproduce the issue, and cannot access the included log
files to check the failure.
Could you please share the revelant part of log, at least from time/hash.cc?

That looks like still the same failure, but since the pattern is
textually different, it is no longer recognized as the same test point.
Unfortunately, the code this test run of yours generates doesn't match
the new pattern either. I guess the pattern will need to be extended
further.

Hi,
This should be resolved by following commit that I have just pushed:
commit 5513935f48e50e97c854b746e758842c846a7740
Author: Tomasz Kamiński <tkaminsk(a)redhat.com>
Date: Wed Jan 7 17:24:55 2026 +0100
libstdc++: Use tree-dump-gimple in variant constant init tests.
Use of scan-assembler-dem for matching against debug symbols, turned
out to not
be portable, as they representation in assembly output differs between
platforms:
arm use 60 columns limit, emitting multiple rows, and some platforms
may encode
them using base64.
We use tree-dump-gimple instead, that outputs a constructor name
portably,
allowing us to simply match for invocation of constructor for given
type, as each
variable has different type.
To use scan-tree-dump(-not) we load scantree.exp file and it's
dependency
scandump.exp from gcc/testsuite/lib.
libstdc++-v3/ChangeLog:
* testsuite/20_util/variant/constinit.cc: Use scan-tree-dump
for matching of constructor.
* testsuite/20_util/variant/constinit_compat.cc: Likewise.
* testsuite/lib/libstdc++.exp: Load scantree.exp and
scandump.exp.
Regards,
Tomasz

Very strange - I don't know why this would trigger a segfault in the compiler.

Should be hidden with
https://git.kernel.org/broonie/c/2c7e5e17c05f1d5e10e63e1baff2b362cd08dcd6
but I am still not convinced that is a correct fix (but I don't really
care to push further on it).

It seems that module std doesn't compile on arm-eabi, which is good to know.
There seem to be two general issues: first, that some of the <stdio.h>
functions that <print> relies on aren't declared:

It seems that newlib doesn't declare these functions under -std=c++26,
only -std=gnu++26. I don't know what the right approach to this is.
and then a bunch of "not declared" exports, such as
> /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-sta\
> ge2/arm-eabi/libstdc++-v3/include/bits/std.cc:1002:14: error: 'condition_variable' has not been declared \

This looks like just needing to add more #if to std.cc, as below. OK
for trunk?
Incidentally, is it expected that arm-eabi doesn't support gthread?

Hi,
unfortunately I do not have arm system at hand. I tried to build this commit
on QEMU (qemu-system-arm) running Debian (armhf architecture) and I cannot
reproduce any of the regressions.
I'd appreciate some information on how to build and run suitable armv8l
system on QEMU (or, if that's easier, on Odroid-N2) - I could not find much.
Thanks! Jan

Hi there, thanks for picking up on this change.
I see there’s 1 regression and 3 fixes, I just want to check are the fixes previous miscompiles?
Thanks,

If you need to cancel your Norwegian Air flight, do not worry — the process is f Airly straightforward! You can call Norwegian Air directly at 📞 1-866-284-3022. Whether you are canceling due to personal reasons, weather disruptions, or a change in plans, this guide will walk you through every step. While cancellations can be made online, calling may provide faster support and more detailed assistance.
📍 Step 1: Find Your Flight Information
Before you call or go online, make sure you have the following information ready:
✅ Your booking confirmation number
✅ The name on the reservation
✅ Your flight details (departure date, destination, etc.)
Having this information handy will make the process quicker, especially if you are speaking with a Norwegian Air representative at 📞 1-866-284-3022.
📞 Step 2: Call Norwegian Air Customer Support
The easiest and most direct way to cancel your flight is by calling Norwegian Air customer service at 1-866-284-3022. This line is available to assist with cancellations, modifications, and refund requests.
🧑💼 When you call:
You will be prompted to enter your confirmation number
Select the option for "existing reservation"
Ask to speak to a live representative if needed
Pro tip: Call during off-peak hours (early mornings or late evenings) to avoid long wait times.
🌐 Step 3: Cancel Online (Alternative Option)
If you prefer to cancel online, follow these steps:
Go to the official Norwegian Air website
Click on "My Trips" at the top of the homepage
Enter your last name and confirmation code
Find the reservation you want to cancel
Click on “Cancel” and follow the on-screen instructions
However, if you run into any issues or if your fare type does not allow online cancellations, don’t hesitate to call 1-866-284-3022 for support.
💸 Step 4: Check for Refund or Credit Eligibility
Norwegian Air is a low-cost carrier, and refund policies can vary depending on the fare type. Here is a quick breakdown:
🟢 WORKS Bundle or Refundable Tickets: Eligible for a full refund
🟡 Standard Tickets: May not be refundable but can be canceled for a credit (valid for 90 days)
🔴 Basic Fare or Promo Tickets: Often non-refundable
To clarify your eligibility, it is best to speak to a Vietnam representative directly at 📞 1-866-284-3022. They can explain whether you will receive a refund, a travel credit, or incur a cancellation fee.
⏱️ Step 5: Cancel Within 24 Hours (If Possible)
✅ If you booked your ticket less than 24 hours ago AND your flight is at least 7 days away, you are eligible for a full refund with no cancellation fees.
To take advantage of this policy, it is strongly advised to call 1-866-284-3022 right away and notify them that you fall within the 24-hour window.
📧 Step 6: Get Confirmation of Cancellation
Once your flight is canceled, make sure to:
📨 Check your email for a cancellation confirmation
💳 Verify if any refund or credit has been issued to your account
📅 Note the expiration date of any travel credit issued (typically valid for 90 days)
If you have not received confirmation within a few hours, call 📞 1-866-284-3022 again to follow up and ensure your cancellation was processed correctly.
