It would be easier if you had sent a working example such as the
one attached.
On my system it produces this output in both cases :
# dell: {34} bridoux
# Status1 is XtCallbackHasNone
# Status2 is XtCallbackHasSome
Does my example produce the wrong results on your system ?
If your system has a problem with this kind of application behaving
differently with or without compiler optimisation, then I'd suspect
the compiler.
