Comment (by muks):

 Looks like WTERMSIG returns the signal upon core dump:

 {{{

 #include <stdio.h>
 #include <unistd.h>
 #include <sys/types.h>
 #include <sys/wait.h>

 int
 main (int argc, char *argv[])
 {
   pid_t p;

   p = fork ();

   if (p == 0) {
     while (1)
       sleep (1 << 10);
   } else {
     int status;

     printf ("Child pid %d\n", p);

     waitpid (p, &status, 0);

     if (WCOREDUMP (status))
       printf ("Child dumped core with signal %d\n", WTERMSIG (status));
     else
       printf ("Child exited with status %d\n", status);
   }

   return 0;
 }

 }}}

 Running it produces:

 {{{
 [muks at jurassic ~]$ ./fork
 Child pid 5908
 Child dumped core with signal 11
 }}}

 I'll update the branch for it.
