Wrong SIG returned

[scottmc]

When building CMake we ran into some failed test cases. One of them was test processes. Here's a sample program that shows a difference between Haiku and Linux, that Bill Hoffman wrote up:

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

int main()
{
 int status;
 pid_t pid = fork();
 if(pid == 0) { *(int*)0 = 0; return 1; }
 while((waitpid(pid, &status, 0) < 0) && (errno == EINTR));
 if(WIFEXITED(status))
  {
   fprintf(stderr, "exited %d\n", (int)WEXITSTATUS(status));
  }
 else if(WIFSIGNALED(status) )
  {
   fprintf(stderr, "sig %d\n", (int)WTERMSIG(status));
 }
 return 0;
}
hoffman@hythloth:~$ ./a.out
sig 11
hoffman@hythloth:~$

That was on a linux box.  On Haiku it prints sig 9.

Adjust the summary as needed as I didn't know what to call this one.

BeOS also shows sig 11 like linux

I didn't think anyone would care, so ATM we send a SIGKILL when a segment violation occurs and there's no SIGSEGV handler. Will change that later.

Fixed in hrev27757.
