If you suspect a bug in emulation, then please try narrowing it down to
the machine instruction that produces the wrong result, you might be able
to track it down in your Fortran program by single-stepping the program in
GDB. Then post the instruction including the encoding (`disassemble /r'
issued in GDB will include it in output), the inputs, preferably as hex
patterns, and the output produced (or action taken if e.g. a signal is
raised instead) that you think is incorrect.
