Hi Nick,

Looks like some glitch in the Assist parser. I've been able reproduce it, just as you said - Typed "::Form", switch to other file and back and theide crashes, saying:

Out of memory!
Requested size: 2684354580 B
U++ allocated memory: 3952556 KB

It apparently falls into endless loop somewhere in the parser, adding more and more items into a Vector that holds the information about parsed code. The stack backtrace for completeness:
