--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> ---
I've just used gcc110 and gcc112 machine (ppc64 and ppc64le) and both print
following stack-trace in the tsan error:
#0 memset
../../../../libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:709
(libtsan.so.0+0x55abc)
#1 __GI___pthread_mutex_init <null> (libpthread.so.0+0xf2ac)
#2 Thread1 c-c++-common/tsan/race_on_mutex.c:12
(race_on_mutex.exe+0x10000f00)
I also verified that non-sanitized version in gdb also has missing source file
for the __GI___pthread_mutex_init function. Thus '<null>' is here proper value.
Can you seurer test the problematic ppc64 machine where you see:
#1 <null> <null>
What do you see in gdb if you put a breakpoint to memset function?
Thanks
