Produces 1 regression: | | regressions.sum: | Running acats:chapter c4 ... | FAIL: c41303a

Used configuration : *CI config* tcwg_gnu_native_check_gcc master-aarch64 *configure and test flags:* none, autodetected on aarch64-unknown-linux-gnu

We track this bug report under https://linaro.atlassian.net/browse/GNU-1648. Please let us know if you have a fix.

I filed https://gcc.gnu.org/bugzilla/show_bug.cgi?id=121494 and will be looking into later tonight or tomorrow. It also happens on s390x which gives me a hint of where to start to try to reproduce it on x86_64.

Hi Andrew, thanks for the heads-up. However, I'm not sure to follow: you fixed this PR on 2025-08-12 (about 1 month ago).

Thanks,

Christophe

Thanks, Andrew
