Crystal: Heap overflow on incorrect syntax "%w("

[veelenga]

The following breaks the compiler:

$ crystal eval "%w("
Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS
$ crystal eval "%i("
Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS

Looks like a heap overflow related problem.

Reproducible with Crystal 0.23.1 and master 3c7ed6535

Cool! That just killed an open Sublime Text editor I had 😆

It's a jinxed bug! Beware of disappearing cats next!
