EH does not work with 1.0.2 on IRIX

[Frank Patz <fp at contact dot de>]

Hi!

I just downloaded egcs 1.0.2 and compiled & installed on an IRIX 5.3
box.
I thought exception handling works with egcs, but all I got (even in the
simplest cases) when I try to throw is an abort. Did I miss
something?


------ exc.cc ------
#include <stdio.h>

int
main()
{
  try {
    printf("try block\n");
    int i = 2;
    throw i;           // program aborts here
  } catch (int x) {
    printf("caught %d\n", x);
  }
  return 0;
}

Running the program gives me:

frank@lulu$ ./exc
try block
Abort (core dumped)


This is the output from "c++ -v ...":

frank@lulu$ c++ -v exc.cc -o exc
