[Linux, OpenAL] "Stat Music" locks ZDoom on streamed formats

I found this out while playing Mayhem Mansion - If the music is being streamed while using OpenAL, typing "Stat Music" can cause ZDoom to crash. I actually got an access violation several times. Unfortunately, the crash output was garbage. I'll see if I can grab something readable, I may have to configure GDB libraries again.

But I can reproduce this each time lately, so that's... progress. GCC 6.1.0.

Found out what it was. it's Timidity causing the crash. Hmm.

now I'm curious, what was going on ?

A simple programming error. The streamer assumed a buffer, but Timidity uses a pipe to stream its data in. And querying some info from the buffer obviously failed.
