Bug ID: 54732
           Summary: schedsvc:atsvcapi & schedsvc:rpcapi crash on a fresh
                    wineprefix
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: taskschd

schedsvc:atsvcapi & schedsvc:rpcapi crash on a fresh wineprefix.
The issue is the same for both tests so I'll focus on the latter:

$ rm -rf ~/.wine && WINEDEBUG=schedsvc ./wine
dlls/schedsvc/tests/i386-windows/schedsvc_test.exe rpcapi
rpcapi.c:64: Tests skipped: Can't connect to Scheduler service: 0x6d9
0020:rpcapi: 0 tests executed (0 marked as todo, 0 as flaky, 0 failures), 1
skipped.

What really happens is that the call to SchRpcHighestVersion() crashes even
before reaching the TRACE() statement. And schedsvc:rpcapi interprets that as
being unable to connect to the scheduler service.

Running schedsvc:rpcapi multiple times does not help. However if one runs
taskschd:scheduler once in that wineprefix, then there is no problem:

$ rm -rf ~/.wine && ./wine dlls/taskschd/tests/i386-windows/taskschd_test.exe
scheduler
...
# Wait until sure that Wine has fully shut down
$ sleep 10; ./wine dlls/schedsvc/tests/i386-windows/schedsvc_test.exe rpcapi
rpcapi.c:268: L"<!-- Task definition created by Wine -->\n<Task
...

In particular this means that when submitting a TestBot job for these tests,
they systematically skip which prevents detecting failures.
(For merge requests there is one 32-bit only full WineTest run which would
catch at least some regressions.)

--- Comment #1 from François Gouget  ---
Another way to prevent the crash is to run mstask:task before. This is why the
test works in full WineTest runs.

mstask:task schedsvc:rpcapi => works
  taskschd:scheduler schedsvc:rpcapi => works
