Dan, thanks for replying so quickly.
The bug also happens in 'real' code.
This is only a very reduced showcase code for the bug,
the bug also occurs in some (pretty big) code of mine
where
if (0)
is actually
if (!some_function(....))
i.e. if the function failed, jump to the failure label.
I believe the -O0 -g does not let gcc optimize the
if (0) away; however, if it does, you'd have to place
some dummy function in the if.
Regards,
Claus
