> Any comments about this version? a new workaround solution :)
Yes, one comment: I think it's ugly :)
These aliasing errors are not reliable so I think we can disable it (like
Linux does).
But in case you don't want to disable the warning, please add a comment to your
workaround to explain it is caused by GCC strict-aliasing check.
