      Description

      Following lines of code lead to a debug assert:

      ...
      QDate dt1(1900, 1, 1);
      QDateTime dt2 = dt1.startOfDay( );
      ...

      If you change the date (1901, etc), everything seems to work correctly.

      This code is part of following function, which therefore also leads to an assert:

      bool QDateTimeParser::fromString(const QString &t, QDateTime* datetime) const

       My Qt build links statically to ICU 70.1.

      (See discussion for details of the custom static ICU build and configuration to enable Qt to cross-compile to 32-bit with it, starting 31 Mar '22.)
