Hmmm... system() returns a "wait status" that can  be examined using the
macros described in waitpid(2), and we have:

/* If WIFEXITED(STATUS), the low-order 8 bits of the status.  */
#define __WEXITSTATUS(status)   (((status) & 0xff00) >> 8)

So this rather looks like a 139 exit status to me... Not sure how
this can happen though.
