Revisit to Threads and Exceptions

[mdp@mindpass.com]

Hi gcc's

My program crashes when I have several threads throwing exceptions BUT it
only crashes when I use gcc-2.95.2 and not my system default gcc
(egcs-2.91.66)

Take a look at my program:
#include <stdio.h>
#include <pthread.h>

#define NUM_THREADS 10
pthread_t t[NUM_THREADS];

void * throwcatch(void *p) {
  while(true) {
    try {
      throw 1;
    } catch(...) {
    }
  }
}

int main(int argc, char **argv) {

  int rtn, idx; 
  unsigned long int ret;
  for(idx = 0; idx < NUM_THREADS; idx++) {
    rtn = pthread_create(&t[idx],NULL,throwcatch, NULL);
  }

  for(idx = 0; idx < NUM_THREADS; idx++) {
    pthread_join(t[idx], NULL);
  }
}


I'm running an Intel RedHat 6.1 installation, and have manually installed
gcc-2.95.2 with the following configure string:
./configure
--with-gcc-version-trigger=/pack/gcc-2.95.2_kernel-2.2.12/src/gcc/version.c
--host=i686-pc-linux-gnu --prefix=/pack/gcc-2.95.2_kernel-2.2.12
--norecursion --enable-threads 

The error occurs more easily (after a few secs) when running on a multi CPU
box, but eventually it also crashes on a single CPU (may take several
minutes).
Is this a bug in gcc-2.95.2 or is it a misconfiguration of my system?
