Why wait? I'll tell you now.

Wanna crash the compiler? There's a pragma for that. :)

#pragma clang __debug crash

This will make the compiler crash. In fact, there's a whole bunch of __debug pragmas which all make the compiler die in different ways. Take a look at lib/Lex/Pragma.cpp:981 to see all the __debug pragmas.
