crash while parsing source files

Jenna:
No idea at the moment.

At build time, did you use a clean source-tree ?

jarro_2783:
one of the computers did, I'll redo the others and see what happens.
I'll try breaking at that function that gets called lots so that you can get a backtrace of what it was doing before it died.

jarro_2783:
backtrace stopping at the point where it goes crazy

edit: I just noticed going a few functions down that the oldToken pointer starts being the same.

Jenna:
Are you able to create a demo-project (as small as possible), that leads to the crash ?

I see why it crashs (most likely):

--- Code: ---parentToken = (Token *) 0x1
--- End code ---
in RemoveToken will reliable lead to a crash, because it should either be a vaild pointer or 0.

jarro_2783:
www.cse.unsw.edu.au/~jarrydb/cbcrash.tar.bz2

changing the file parser.hpp and saving it causes the crash.
It also needs boost 1.38, and I couldn't get it to crash without having that in my search path, so when it asks for the boost global variable you'll have to give it the path to 1.38.
