Comment 30 for bug 1659172

P.S. Sorry if I sound a bit skeptical towards your undoubtedly very systematic tests, but from everything I learned so far the issue is highly un-systematic, so it's hard to trust tests one does today as results might differ tomorrow. I did not only think once that I finally found the source (no more hangs!) only to experience the same issues again with seemingly identical parameters some time later... (For all I know it might be an uninitialized variable / invalid pointer and behavior may change on every run depending on the memory layout).
