Hi,
on test.winehq, WinME systems always report 8 rc=MMSYSERR_INVALPARAM
errors. However, when running a MSVC compiled binary (as found in
testbot job #4990), no such error occurs.

Likewise, Octavian Voicu's machines saw no failure with the MSVC
binary, but constantly produce red color on testbot.
This could
- Either be a bug in testbot's MingW (compilation or includes)?
What's the difference between testbot compilation and Paul Vriens'?
- Some weird memory corruption affecting only WinME?
- a bug in my tests?
Those INVALPARAM errors happen since May. However my May-19 patch did
not change the tests that since fail, so it must be a side effect of
something else.
1. dwBytesRecorded is left uninitialised, which may produce random
results -- if it were used.
2. dwOffset is now set to 0xDEADBEEF; previously uninitialised.
Yet that does not explain why MSVC's and Paul's cross compiled binary succeed.
Paul and I found a bug in the mingw includes once. Perhaps that's another
instance?
How to proceed from here?
