      When I create QDateTime objects in two threads at the same time, sometimes I get value from thread 1 in the thread 2. I can reproduce it on Android, but not on my Linux Laptop.

      Test program in the attachment run two treads, and each thread creates uint variable, then creates from it QDateTime and compares toTime_t() and initial value. After several seconds, the values does not match.
