--- Comment #1 from Bernhard Übelacker bernhardu@mailbox.org --- Created attachment 71344 --> https://bugs.winehq.org/attachment.cgi?id=71344 Another backtrace with PDB file available.
The crash seems to happen because "nsObserverService::AddObserver" contains a "NS_ENSURE_VALIDCALL".
This "NS_ENSURE_VALIDCALL" calls "NS_IsMainThread" which returns, as far as I see "0".
Therefore this line gets executed: 212 MOZ_CRASH("Using observer service off the main thread!"); \
This leads to the following line in wine-gecko-2.47.2/mfbt/Assertions.h 235 *((volatile int*) NULL) = __LINE__; \
And this matches the crashing instruction: 0x000000018007de47 xul+0x7de47: movl $0xe3,0x0000000000000000
Maybe the MOZ_CRASH_ANNOTATE should output something to stderr in this case.
