I thought so, too.

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
