[Lazy]

I'm writing a class to make BSP reading easier ( for me anyways ).
The problem is that on certain maps reading the texinfo lump will cause some serious bugs. What's wierd is that it crashes when I try to free memory that the BSP class used ( overloaded delete operator ). If I comment out loading texinfo it works fine.

I know it's a problem with large data amounts because of the following scenario...

1. Tried to load ns_mineshaft - Crash
2. Tried to load ns_siege007 - Worked

Alot of the numbers produced by my class so-far show siege to be quite small as compared to the other maps ( when they loaded ).

Any suggestions?
I already tried using "open" instead of using "fopen" to see if that would help but with no luck. I also do not want to resort to using the windows file I/O functions.

Any help is appreciated.
