I just tried running midl on dlls/oleaut32/tests/tmarshal.idl and it complained: tmarshal.idl(83) : error MIDL2270 : duplicate UUID. Same as : ItestDual [ Interface 'ITestSecondDisp' ]
This doesn't seem like it's intentional. But just giving ITestSecondDisp a new uuid causes the following test failures on Windows: tmarshal.c:1861: Test failed: external_connections = 2 tmarshal.c:1864: Test failed: external_connections = 2 tmarshal.c:192: Test failed: fLastReleaseCloses = 1 I could try to figure this out, but it's probably better if someone familiar with the subject could have a look instead. (also, assuming this is a bug in the test, we might want to add that check to widl, it seems pretty useful ;]) Thanks, Thomas
