After we cleaned out the most significant crashes from our game, this version of the fmod crash came to the top. This crash doesn’t happen that often, about 1 time per 1000 user sessions. I am attaching stacks of falls from significant threads.

Hi,

Thank you for bringing this to our attention.

Could I please grab your FMOD version numbers?

3

We are using FMOD version 2.03.08

Thanks for the info.

A similar issue in Unity was identified in unity with a potential solution shared here: [Bug][2.02.06] Android startup crash - #23 by jeff_fmod.

Are you using a game engine? Are you able to share any reproduction steps?

No, according to the link you provided, it’s a completely different stacktrace. There, the drop occurs at the moment of fmod initialization. In my case, the drop occurs when FMOD is called FMOD::Studio::System::release() .

Sorry, but this option is difficult to repeat in the sample. As far as I understand, this is a loss of connection with bluetouch headphones at the moment when the game releases fmod resources.

Thank you for checking that.

Unfortunately, testing your theory I was not able to reproduce a crash. We are still investigating other options.

Would it be possible to upload the full tombstone file to your profile?
