According to FPL:
-O does not change anything in debugging the little code. [...]
Then this is indeed a bug. Thanks for the report!
[...] where GPC should not simplify anything as there is nothing to simplify.
Oh - GPC will find something to simplify, but not that much.
If it is only debugging problem, the problem should go away when putting the breakpoint far away, isn't it? And it does not!
Then there is also a bug in your program.
Please insert some `writeln' statements between the lines of your program. If the resulting output is too much, write to a file instead of the screen which you can examine with a text editor or `less' afterwards.
(sorry Peter if I mail directly to you, it is to speed up the mailing)
That's okay as we `cc' the mail to the list.
Good luck,
Peter
