It's an fpe. These occur when there is an overflow/underflow
or other problems such as division by zero. Some programs
do not except them to happen in which case they can be masked
with
#include <floatigpoint.h>
main()
{
fpsetmask(0);
/* the rest of the program */
}
See fpsetmask(3).

If so, the call to fpsetmask should fix your problem.
