Subject: Wrong child process exit status if core dump / seg fault

Hi all,

when a child process exits with core dump or seg fault (Windows/Linux),
I cannot obtain the correct exit code.

I tried the following
----------------------
   system("test.exe");
   # or
   `test.exe`
   # or
   sp = spawn("test.exe");
   Process.wait(sp)

   puts $?
----------------------


The exit code is always 0. In command shell, I can test it with e.g.
----------------------
   test.exe && echo "Success"
----------------------

"Success" is not printed due to exit code of test.exe.

test.exe could be a simple c++ source file like this:
----------------------
   class A {};
   int main() {
     throw A();
     return 1;
   }
----------------------



--> How can I find out the exit code in ruby for child processes which
do not terminate gracefully?

Thank you,
alll
