    Description

      Simply `QTime::fromString("00:00.000", "m:s.zz")` will crash the program if building with icu-enabled Qt 6.8 (e.g. MSYS2 repo's Qt).

      See https://github.com/msys2/MINGW-packages/issues/22308 for detailed reproduce steps.

      The following is the call stack, seems we have infinite recursion which caused stack overflow:

      QIcuTimeZonePrivate::data -> QTimeZonePrivate::abbreviation -> QTimeZonePrivate::displayName -> QIcuTimeZonePrivate::data -> ...

      The attachment is the same reproducible test program, but remember you need to test against a ICU-enabled Qt. Using MSYS2's Qt would be enough.
