Well, obviously [and "to begin with"], you've never heard of
things along the lines of "#include <pthread_exception.h>"...

spe207.testdrive.compaq.com> what /shlib/libpthread.so|grep DECthreads
         DECthreads version V3.18-138 May 12 2002

Go...

Hi There! Greetings from the ``yellow zone.''

Exception: Attempted stack overflow was detected (dce / thd)

Indeed. ;-)

spe207.testdrive.compaq.com> cat ceh.c

#include <stdio.h>

#include <pthread.h>
#include <pthread_exception.h>

void operation()
{
  char buffer[128];
  memset( buffer, 0, sizeof( buffer ) );
  operation();
}

void* my_thread( void* p )
{
  TRY {
    printf( "\nGo...\n\n" );
    operation();
  }
  CATCH_ALL {
    printf( "Hi There! Greetings from the ``yellow zone.''\n\n" );
    pthread_exc_report_np( THIS_CATCH );
    TRY {
      RERAISE;
    }
    CATCH( pthread_stackovf_e ) {
      printf( "\nIndeed. ;-)\n\n" );
    }
    ENDTRY
  }
  ENDTRY
  return NULL;
}

int main()
{
  pthread_t tid;
  pthread_create( &tid, NULL, &my_thread, NULL );
  pthread_exit( NULL );
}
