A lot of you have played my map The Sorcerer's Defense, and many of you probably crashed while doing so. Well after trying everything conceivable I finally narrowed the crashing down to - of all things- the music triggers. The latest version published a couple of weeks ago removed these music triggers (and made no other changes) and I have not had any crash reports since then.
Here's how I was handling custom music: I had two different music sets, one for the build phase and one for the wave phase. Each music set had a Sound object containing all of the sound files, as well as a Soundtrack object referencing only the one sound object. I basically copied everything that Blizzard did in their implementation.
To switch between the two I used triggers to change the soundtrack and set it as default.
Anyway I don't know exactly why that setup was causing crashing, but if anybody is having similar issues in their map - try disabling your custom music and see if that fixes it! Because debugging random crashing is not fun.
