Hi,
This failure is a false detection caused by a floating-point precision error in fast-math. Please ignore the mail. We'll update the test.
Sorry for the noise.

Thanks. See https://gcc.gnu.org/PR120929.
Qing, you may be able to reproduce it on x86-64 with ./configure
--with-build-config="bootstrap-ubsan" && make -j$(nproc) -l$(nproc) too.

Could you file a glibc bug for this please? It needs some analysis to
see if it's an FP or not.
There's actually a suppression for -Os already there:
if (elem < table_size)
{
/* Compare the byte sequence but only if
this is not part of a range. */
/* The compiler might warn that idx may be
used uninitialized, however it will be
reached iff elem < table_size which means
that it was properly set in the loop
above. */
DIAG_PUSH_NEEDS_COMMENT;
DIAG_IGNORE_Os_NEEDS_COMMENT (8, "-Wmaybe-uninitialized");
if (! is_range
# if WIDE_CHAR_VERSION
&& __wmemcmp (n, &wextra[1], c1) == 0
# else
&& memcmp (n, &extra[idx + 1], c1) == 0
# endif
)
{
n += c1 - 1;
goto matched;
}

Hi,
As discussed in https://github.com/llvm/llvm-project/issues/141928 , this is an error of the test program Fortran/0614/0614_0005.f. Please ignore the mail, sorry.
We've fixed the test internally. It will be pushd to the GitHub.
