Hello 

do you have an idea about the possible cause of this exception when calling the FreeBASS function?

   First-chance exception at 0x7853be76 in VB6.EXE: 0xC0000005: Access violation reading location 0x6c9cf1e4.

    bass.dll!7853be76()    
    [Frames below may be incorrect and/or missing, no symbols loaded for bass.dll]   
    bass.dll!785410ba()    
    bass.dll!785410ec()    
    bass.dll!78542402()    
>   MyDll.dll!BassWrapper::FreeBASS()  Line 806 + 0xd bytes   C++
    001aeef4()   

Kind regards

Is "FreeBASS" just BASS_Free?

Are you able to reproduce the crash? If so, please get a dump file from it. You can use Visual Studio's "Save Dump As..." option to do that, and then ZIP and upload it here:

Hello,

yes, the call happens on the call to BASS_Free: if it happens again I will send the dump.
It must be related to the fact that some HSTREAM has not been freed.

Kind regards

It must be related to the fact that some HSTREAM has not been freed.

That shouldn't be a problem, as BASS_Free will free any streams on the freed device. But if you're using BASS via a wrapper DLL (I see "MyDll.dll!BassWrapper" in the posted call stack ), note you shouldn't call BASS_Free (or really anything outside of KERNEL32.DLL) in the wrapper's DllMain function.
