gdb doesn't like static code too much but the following is a backtrace of the
crash:
Program received signal SIGSEGV, Segmentation fault.

Which is
static inline int

{
return __gthrw_(pthread_cond_broadcast) (cond);
}
It looks like pthread_cond_broadcast is not correctly bound, as the disassembly

The complete statically linked __cxa_guard_release looks like:

What happens if you force libpthreads to be all linked in?

Richard,
I think I know what happened. Could you please do an
nm a.out|grep " pthread_"
or your executable and send that to me? It seems that we need to change glibc
unfortunately. Here is code at the end o

It seems that this is only a problem for a static link. And it would
presumably work fine if we had strong references to the functions we need. So
let's just do this at the end of guard.cc:
#if !defined(__PIC__) && defined(_

The only at least partially workable way of linking statically against NPTL
libpthread.a is -Wl,--whole-archive -lpthread -Wl,--no-whole-archive.
There is just a huge amount of issues if you don't have everything in there i

Yes, the analysis from comment #6 looks correct - Jakub, can you take care of
the
required glibc fix? I'll check if Ians trick works as well.

Linking pthread with --whole-archive works.

This is not a bug on the GCC side.
