This happens inconsistently in most of the programs I write, but always during some floating point calculations -- in one case during a call to 'floor'. It also happens consistently when ever I try to run a program written in Objective-C, even one which does almost nothing:

#import <objc/Object.h>
int main()
{
id myobject = [Object alloc];
printf("Hello World!");
}

produces this when i run it:

F:\JSTUFF\OCSAMPLE>tst
Exiting due to signal SIGFPE

If anyone has any ideas, PLEASE write me. Thank you.
