Description
found this when tracing a huge memory leak in my application (in which I pass smart pointers to QtConcurrent::run).
related to usage of: "releaseThread();
; reserveThread();" in my threads
attached testcase triggers the issue
(also: attached testcase hangs about every 10 times I run it)
issue disappears when removing the releaseThread() and reserveThread() calls
