--- Comment #21 from Paul Woegerer <paul_woegerer at mentor dot com> ---
I'm facing the same problem as Stefan. Interestingly it does not matter when
liblttng-ust.so gets opened from an ldaudit shared object. In my example I
dlopen liblttng-ust.so from the la_preinit() callback in my ldaudit.so. The
result is the same:

Program received signal SIGSEGV, Segmentation fault.
0x00005555555657a0 in add_to_global (new=new@entry=0x7ffff78509f0) at
dl-open.c:94
94              = ns->_ns_main_searchlist->r_nlist + to_add + 8;


Opening any other shared object from la_preinit() works just fine. Also
applying Carlos patch glibc-ldaudit-tls-segv.diff does unfortunately not fix
the problem.

I have attached a dump that I created with:
LD_DEBUG=all LD_AUDIT=$PWD/ldaudit.so ./gmontest 2> LD_DEBUG.out
