Description

Hi, this is copied from the GH issue I opened: https://github.com/qt/qt5compat/issues/3

I've discovered running the test suite on a platform which does not support unaligned access, that under tst_qt5compat_json, the test tst_QtJson::invalidBinaryData() invokes a lot of UB by issuing unaligned accesses. This is the only test which has this problem - the rest of the test suite is perfectly fine.

Below is a sample output from UBSAN, compiled with -fsanitize=alignment. This also includes qtcore-6.8.0 built with the same flags, since some of the accesses technically occur there.

Although this was discovered by running on a platform on which unaligned accesses are illegal, unaligned access is always undefined behavior on all platforms and will always be caught by UBSAN. That's why I have not made this ticket platform-specific.
