But this time I can attach with gdb:

0xbb7fa407 in ___lwp_park50 () from /usr/libexec/ld.elf_so
(gdb) bt
#0  0xbb7fa407 in ___lwp_park50 () from /usr/libexec/ld.elf_so
#1  0xbb7f25c5 in _rtld_exclusive_enter () from /usr/libexec/ld.elf_so
#2  0xbb639275 in __register_frame_info () from /lib/libgcc_s.so.1

I see that libexecinfo has a weak reference on __register_frame_info(),
but I do not understand how it relates to the code it contains.
