 A more detailed backtrace when firefox was compiled with CFLAGS+=-g:
 
   Core was generated by `shlibsign'.
   Program terminated with signal 11, Segmentation fault.

 The only suspectable ting I was able to find is the comment 
 
      * NB: The destructor logic seems to have a bug so it isn't used.
      * NBB: Oh really? I'm going to give it a spin - AOF 19 June 1998.
      * More info - the problem is that pthreads calls the destructor
      * eagerly as the thread returns from its root, rather than lazily
      * after the thread is joined. Therefore, threads that are joining
      * and holding PRThread references are actually holding pointers to
      * nothing.
