Greetings


Another bug with long longs...

When the following program

======================= file tbug1.c ======================
#include <stdio.h>

long long int buggs = 123;

double trouble;
void
main()
{
  trouble = (double) (buggs & 0x7FFFFFFFFFFFFFFFLL);
  printf ("%f\n",trouble);
}
==========================================================

is compiled (using DJGPP 1.06) with

     gcc -o tbug1 tbug1.c

no errors are reported (and the resulting program runs OK).

But with

     gcc -O -o tbug1 tbug1.c

GCC crashes, saying     "Exception 117 at eip=a9cf1", and a
(random) character appears at the top screen line.
