Normally the exit code includes the signal that caused the termination..

Code:

    WIFSIGNALED(stat)
          Evaluates to a non-zero value if status  was  returned
          for a child process that terminated due to the receipt
          of a signal.

    WTERMSIG(  stat)
          If the value of  WIFSIGNALED(stat) is  non-zero,  this
          macro  evaluates  to  the  number  of  the signal that
          caused the termination of the child process.

So you would need to look up the macro WTERMSIG on your system in the /usr/include directory and decode 137 to deduce the signal number. Then look up the signal number in sys/signal.h or similar. Look for things like SIGSEGV, SIGKILL etc.

I have a sinking feeling that the macro will say subtract 128 to get the signal number, leaving 9 which is SIGKILL. Which is normally an external intervention and somebody doing "kill -9 pid".
