It helps a lot to have a compilation log to start with when these hard 
to reproduce failures happen. Those two tests test the compilation parts 
of the WB API.

I ran into another issue in these tests - the compile()-method in 
CompilerWhiteBoxTest is not reliable unless the invocation counter decay 
is turned off. I added a check of the UseCounterDecay-flag in that 
method so that no one will miss it by accident.

Best regards,
