Was this a QEMU bug or an issue in your program? But interestingly whenever > my app crashes it always displays the same "floating point exception" > message.

Alternatively, can you strip it down to a super-minimal program that replicates just this one issue? Pasting us a GDB backtrace of the failure might help as well.
