On Linux/hppa, I see a test failure:
$ cat test-strerrorname_np.log
Segmentation fault (core dumped)
FAIL test-strerrorname_np (exit status: 139)
The gdb stack trace reveals the cause:
(gdb) where
#0 0xf95c4920 in ?? ()
#1 0x000113c4 in main () at ../../gltests/test-strerrorname_np.c:1130
Here is a workaround.
2023-11-21 Bruno Haible <br...@clisp.org>
strerrorname_np: Work around glibc bug on HPPA systems.
* m4/strerrorname_np.m4 (gl_FUNC_STRERRORNAME_NP): Test also
strerrorname_np (ENOSYM).
* lib/strerrorname_np.c (strerrorname_np): Update comments.
* tests/test-strerrorname_np.c (main): Likewise.
* doc/glibc-functions/strerrorname_np.texi: Mention that glibc 2.37
still needs a workaround.
