As most of you are aware, a signed 32-bit time_t overflows in 2038. Linux has recently deployed "time64_t" (by certain values of "recently", as in 2015, see [1]). Bug report QTBUG-110429 says QMutex and QSemaphore don't work after the overflow, so I prepared the patch above. It failed in the CI, in the QEMU emulation of ARMv7. The reporter however says that the patch works on real hardware (ARMv7 too). I don't know if this is an emulation bug. It's likely. QEMU's emulation at that lower level is so riddled with bugs that every time a test fails under emulation, I consider it a QEMU fault until proven otherwise. So this is a request for help: can someone who has an interest in 32-bit platforms take the patch forward? I am not that person and I don't even have a development environment for 32-bit. If there's no action within one month, I'll abandon the patch, close the task as "Won't Do" and declare 32-bit Qt will not work past 2038.
