Hi,

thanks for testing. I have to admit the explanation regarding how the various
switches play together went a little over my head, but if you tell me that's
intended behaviour, I'll trust your word on it :)

Just to be sure: For me, this also happens when "-fno-strict-aliasing -fwrapv"
are not added as parameters, I only added those because I saw them mentioned
somewhere in the bug reporting guidelines. If it's still intended behaviour
without them, feel free to close this bug report and thanks for the help!

Cheers,
Lukas
