What?

I think someone has too much fun with ASM.
EDIT: Or not. But it is weird.

This is indeed a strange issue. I tried to reproduce it in both linux and in windows. On windows it worked fine. Though in linux, the game started fine, but with a black screen. Once I removed the "-XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump" jvm flag it started working again. I'd suggest trying different combinations of the jvm flags to see if it's one of them causing the issue.
