It might be just me, but I've seen five very strange test failures today out of about 30 build/test runs. Has anybody else noticed problems?
It smells like the rpcrt4 change.
I thought so, too.
I admit I'm a bit at a loss, how this could happen. Could you create a +seh,+rpc log? And does it go away, if you revert those changes?
I've reproduced it twice now in an hour on two quad-core machines with the script
for try in `seq 1 100` do echo try $try server/wineserver -k || true rm -rf ~/.wine cd dlls/advapi32/tests rm -f *.ok make test cd ../../msi/tests rm -f action.ok make action.ok cd ../../.. done
so it may take me a while to verify that it goes away after reverting the rpc change or to get you a detailed log.
In one of the failures, I got the service.ok failure from above:
service.c:152: Test failed: Expected success, got error 1060 err:rpc:I_RpcGetBuffer no binding service.c:176: Test failed: Expected ERROR_SERVICE_DOES_NOT_EXIST, got 123
In the other, I got a crash in service.ok: ../../../tools/runtest -q -P wine -M advapi32.dll -T ../../.. -p advapi32_test.exe.so service.c && touch service.ok err:rpc:I_RpcGetBuffer no binding err:rpc:I_RpcGetBuffer no binding wine: Unhandled page fault on read access to 0x60481043 at address 0x7bc34227 (thread 0021), starting debugger.. err:ntdll:RtlpWaitForCriticalSection section 0x110530 "?" wait timed out in thread 002a, blocked by 0021, retrying (60 sec) ...
I don't get backtraces much anymore because of that darn deadlock (unrelated to the current problem), and btall doesn't seem to show a crash (though it does have some interesting stack traces); see the attachment.
Austin may have a related crash in rpcrt4_test.exe.so server.c, see http://bugs.winehq.org/show_bug.cgi?id=28383#c2
