[fpc-pascal] FPC 3.2.2 (In)complete Boolean Evaluation on 32bit MacOS

[Pierre Muller]

Hi all,


   I took the liberty to report a bug issue about this problem,
which I was able to reproduce on x86_64 3.2.2 release compiler.

See
https://bugs.freepascal.org/view.php?id=38973
for more details,

Thanks for reporting,

Pierre Muller

> This crashes because Cancel and Cancel^ are always evaluated, even if Cancel is nil.
