Do you have any locale environment / language setting that uses "," as
delimiter? I once ran into a very hard to find similar bug, where
whenever I was using Qt somewhere, stream parsing in all code wanted my
system locale (German, "1,5") instead of "1.5", happily changing all
parameters when parsed.

I don't remember exactly, but there's a way to explicitly set the locale
back in the code or an environment variable if you're working on a
non-English system.

Best regards,
Armin
