This is specific to the 64-bit tests and first happened on 2023-07-10 which
corresponds to the GitLab CI's move to Debian 12 for building the Windows test
binaries (5799e89f15b5). This is confirmed by the fact that test executables
built on Debian 11 still don't get these failures.

In particular this means:
* These failures will show up in the TestBot's nightly WineTest results since
they use the official winetest.exe binaries built by the GitLab CI on Debian
12.
* But they will not happen when testing patches on the TestBot since, so far,
it still builds the tests on Debian 11.
