QTest::QWait Crashes when called multiple times within a loop

I have created a Unit test that crashes consistently.

While debugging the test, I  found that calling multiple QTest::qWait() within a for() loop appears to cause the crash.

I have provided source code for a  QTest-based application that demonstrates the problem.   You can find the source code (.cpp, .hpp, and .pro) in the attached .tar file. 

The test calls QTest:qWait() six times within a for() loop; the for() loop is set to execute fifteen times.  The test consistently crashes during the eighth iteration of the for loop.

I want to understand what I am doing wrong, or report a bug.
