I have two programs that when compiled under the latest version of g++: gcc version 4.1.1 20061011 (Red Hat 4.1.1-30) work perfectly under FC6 but give the error 'Floating point exception' when run under FC5. (The version of g++ in FC5 is 4.1.1 20060525 (Red Hat 4.1.1.-1) When one runs a gdb (in FC5) on either program you get: (gdb) run Starting program: prepdata Reading symbols from shared object read from target memory...done.

When compiled under FC5 g++, the program also works properly. The FC6 machine is an Intel Core 2 Duo, the FC5 machines have Intel 950 (Dual core) chips and are running smp kernels. Is this an incompatibility? - a bug?
Do you have the same kernel, i.e. i386 vs. x86_64, on both systems?
