This appears to happen for both 32-bit and 64-bit Windows machines. The crash appears to happen after all the tests have run. Something related to the datapool clean up sequence is our suspect.
I will look into this more as we prep the 4.5.1 builds this week.
I cleaned up about a dozen small memory leaks in the unit tester that may be causing this problem. The only thing remaining (that I can catch) is a leak out of Qt (really out of iconv).
The issue was found to be an improperly setup bandpass list used in the Path
Angle truth collector. For some reason only Windows didn't have a sense of
humor about this.
