# include <stdio.h>

int main(int c, char *argv[])
{
   long long   i;
   long long   n;

   for (i=0LL; i<63LL; i++)
      {
      n = 1LL << i;
      printf("1 << %d = %lld\n", i, n);
      }

   return 0;

}


%lld is giving 64 bit results for i < 32 and 0 for i >= 32.
>How-To-Repeat:
Execute above program.
>Fix:
None that I can see.   Is 64-bit integer formatting supported by g++ compilers?  Doesn't seem so.
