All compiles here are compiled with the -O2 option for intel (although -O3 and -OS also fail)

The problem occurs because gPlayFileList is 0 and can not be dereferenced. Apparently GCC with O2 or greater optimization will move the dereferencing outside of the loop and actually dereference gPlayFileList before checking numfiles. Is this not a bug in the compiler?

It looks like it's probably a compiler bug. Please file a bug report with a preprocessed version of the source file (such as you'd get by adding -save-temps to the compiler flags) and a copy of the command line used to invoke the compiler. Thanks!
