The application is accessing uninitialized memory. It calls:
- operator new(136)
- assigns this memory to MIXERCONTROLDETAILS->paDetails
- calls mixerGetControlDetailsW
- calls
MSVCP_basic_string_wchar_ctor_cstr((wchar_t*)MIXERCONTROLDETAILS->paDetails+4)
The last call causes crash in some cases (I was not able to reproduce the crash
on my computer). You can check that theory by calling:
memset(paDetails, 0, cbDetails) in mixerGetControlDetailsW.
