#52 Maximum stack depth not checked

[Anonymous]

Hello,

on some files, I had cccc crashing. After investigating, it appears that it occurs when stack_depth becomes greater than MAX_STACK_DEPTH.
My problems were in ParseUtility::tracein at cccc_utl.cc:507, but it could occur at other places too judging by the code.

At each usage to index a fixed size array, stack_depth should be checked to be < MAX_STACK_DEPTH.

Patch attached.

Regards,
Colin
