--- Comment #100 from Tor Lillqvist <[email protected]> 2012-09-09 13:21:24 UTC --- For case II, there is an *awful* lot of recursion going on in hitTestRunner(). By an odd coincidence (?), the recursion ends before the thread runs out of stack space though. But then some thirty call stack slots deeper it does, anyway: #0 0x91aa5ef1 in pthread_mutex_lock () #1 0x000068f9 in osl_acquireMutex (Mutex=0x787e6e0) at /Users/tml/lo/tdf/sal/osl/unx/mutex.c:123 #2
