Hm, this is interesting, as I cannot reproduce this at all:

% cat bt.c
#include <execinfo.h>

int main(void)
{
  void *addrlist[100];
  backtrace(addrlist, 100);
  return 0;
}

% cc -g bt.c -o bt -lexecinfo

(I had pulled the latest sources and rebuilt lib/libgcc_s)

% LD_LIBRARY_PATH=/usr/obj/usr/src/amd64.amd64/lib/libgcc_s gdb ./bt

Can you show me how you've built the example program? In particular, can you
show me output of the compilation command(s) with the -v option added?
