clazy build/tests fail with Qt 5.15.8 - succeed with 5.15.7

STEPS TO REPRODUCE
1.  Build clazy in Ubuntu or Debian development versions with Qt 5.15.8 running tests; 
OR run autopkgtests on Debian or Ubuntu CI infra with Qt 5.15.8
OR build clazy on KDE Neon with their Qt 5.15.8 and tests enabled (Ubuntu 22.04 LTS base and toolchain)

OBSERVED RESULT

Tests fail with:

According to Simon Quigley's investigation, it is caused by https://code.qt.io/cgit/qt/qtbase.git/commit/src/corelib?id=826e076ef53a5809.
