      Description

      The following qtbase test failed:

      # ./tst_qeventloop
********* Start testing of tst_QEventLoop *********
Config: Using QtTest library 6.2.4, Qt 6.2.4 (arm-little_endian-ilp32-eabi-hardfloat shared (dynamic) release build; by GCC 11.3.0), poky 4.0.6
PASS   : tst_QEventLoop::initTestCase()
FAIL!  : tst_QEventLoop::processEvents() 'eventLoop.processEvents(QEventLoop::WaitForMoreEvents)' returned FALSE. ()
Loc: [/usr/src/debug/qtbase/6.2.4-r0/git/tests/auto/corelib/kernel/qeventloop/tst_qeventloop.cpp(218)]

      The test fails with date before and after 2038:

      Flags Date tst_qeventloop result
      None Before 2038 Pass
      None After 2038 N/A (system crashes)
      -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64 Before 2038 Fail
      -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64 After 2038 Fail
