A program I have written (ray tracing sort of thing) is suddenly getting
SIGFPEs, which doesn't stop it from running, but it runs half as slow as it
used to and crashes RHIDE after it finishes. The error occurs when you
change one value from a value lower than 0.9 to one greater than or equal to
0.9. I am now pretty sure it is not a divide by zero, sqrt(-x) or overflow
problem, what else might cause a sigfpe and how can I trace the problem?
Thanks in advance,
Dan
