Freeze on FPU exception with Athlon

The following small program (linked against glibc
2.1.3) reliably
freezes my system (Athlon Thunderbird CPU) with at
least kernels
2.4.0-test10 and 2.4.0-test11-pre5. Even the SysRq
keys do not work
after the freeze.

Older kernels (e.g. 2.3.40) seem to work. Any Ideas?

---------------------------------------

#define _GNU_SOURCE

#include <fenv.h>
#include <unistd.h>

int
main(void)
{
  double a;
  fesetenv(FE_NOMASK_ENV);
  a = 1.0 / 0.0;
  sleep(10);
  return a;
}
