Bug in alpha float->int conversion on AXP



Hi Richard,

is this a bug in the kernel emulation?  Or some kind of glibc/gcc bug?

Andreas

Jensen Box (Alpha EV4, 150Mhz), DEC2000 model 300
>Description:
On a jensen box, some mathematical operations fail (the process hangs and
eats cpu time). examples are:

python -c "print int(1.0)"

or this C program:

#include <stdio.h>
#include <math.h>

int main()
{
  printf("%f\n",floor(0.1));
  return 0;
}

Greetings,

Martin
