Re: Exception on a simple arithmetic problem

This happen during debugging my C code under XCode, compiled for Intel platform,

fVal = 100.0 / (double) fTemp; /* EXC_ARITHMETIC happens here */

The debugger stop and throws EXC_ARITHMETIC message at the calculation line. When the program is in release mode(compile with - O2), this problem never happens during runtime. I am using OS 10.4.3 (8F1111).
What condition makes EXC_ARITHMETIC exception to be thrown under Pentium ?

I suspect that a memory-allocation problem elsewhere has trashed the 'filesize' variable such that it no longer contains a valid numerical value. Try printing it out.
