Uninvited crashes otvdm after playing any sound

[filipetolhuizen]

Playing without sounds works fine, but enabling it, it crashes a few seconds after playing any sound.
Environment:
•OS: Windows 7 64 bits SP1
•Version: dev1685 and earlier builds.

The tail of trace.txt seems to be missing.
I fixed it so that it would not be missing, so try to trace again with the latest version.

Updated trace.txt, funny thing is when it's tracing, sound play twice before crashing.

Turns out if I leave another instance of otvdm(w).exe standing by an .exe and run the game, it doesn't crash.

Here's x32dbg register.

It looks top be crashing while parsing the wav file by reading past the end of the it. The file might be corrupt. I've been testing with a copy from the IA https://archive.org/details/win3_Uninvi3x .

That copy also crashes on the same place for me.

I think I know whats happening. It plays the sound then polls with an empty wav file and SND_NOSTOP waiting for success to indicate completion. The problem is the empty wav file is smaller than the wav header and when it is played it'll crash depending on what happens to be in the space that the end of the header would fill. Windows 10 handles the fault so prevents the crash but Windows 7 doesn't. The trace didn't show this because it uses SND_ASYNC so the crash is in a different thread.

Thanks! It's running fine now.
