Crash playing XM tracker files

Hello. The OldUnreal team is working on an FMOD-based audio driver for Unreal Tournament 99. We are currently seeing crashes when playing certain XM tracker files. We recently upgraded to FMOD Engine 2.1.5 and then to 2.1.7, but the crashes keep triggering reliably. The crashes do not happen immediately. The tracks start playing but then cause a crash after about 2 minutes. Since the tracks are most likely copyrighted, I would prefer to send them directly to whoever can look into this crash. Note: other tracker formats play back fine.

Hi if you send a file to I can look at it

Hi, I have now attached a pre-release build to your profile to see if it solves your problem.

That seems to fix it. Thank you!
