Subject : KDevelop crashes on long comments

Error Class	: software bug
Error Location: class tree
Priority	: medium
Bug Description ---------------------------

KDevelop crashes on comments longer than 2kB.

How to repeat the error -------------------

Open a new .cpp file and enter :
now a lot of characters, at least 3000 of them or so.
If you're lucky, you may even get a permanent busy
cursor or other nice things, much more interesting
than just a crash.

Bugfix or Workaround ----------------------

Sure :)  :
I think I've located the problem in file
classparser/ClassParser.cc at the beginning
( extern char comment[ 2048 ]; )
and file classparser/tokenizer.l at the beginning
( char comment[ 2048 ]; )
The simplest fix seems to be either to use QString
or a dynamically allocated array and an overflow check
in tokenizer.l . Well, maybe the simplest would be to
change that 2048 to something larger, but if I needed
more than 8000 today, maybe someone else would need
even more tomorrow.
