After updating our game to FMOD version 2.2.5 we are seeing this exception in a thread started by FMOD:

Exception thrown at 0x00007FFE544BAE96 (fmodstudio.dll) in java.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

This happens after about 10 minutes of normal operation. Besides a stack trace, we don’t have any useful information to help debug this.

Is it possible we can get the PDBs for at least fmodstudio.dll where the crash happens?

Thanks!

Following up the above (we both work for the same studio) we downgraded from 2.2.5 to 2.2.4 and the segfault seems to be resolved with that version.

Does the crash occur in the FMOD Studio app, or in your game?

The crash is in the game. I think we upgraded our license to get the FMOD source, so we should be able to debug this soon.

Ah yes, I see that you’ve upgraded. Let me know via email ([support@fmod.com](mailto:support@fmod.com)) if you need anything wrt building FMOD from source and also to share the results of your debugging. Keen to see what that crash is…
