Stack overflow.

that`s all the stack has

I commented out the recursion so it never gets called. That should stop it being the cause if it was. Im still getting the error though. P.S its a irrlicht wanna be game with more or less code in it, I have no clue what`s causing the error so I dont know how can I isolate the problem in a minimal example )
P.P.S being an irrlicht program it starts out as a console which then creates the window, however it breaks before any console is displayed.

Sounds like you may have over run an array inside a function, which will screw up the return address and stack.
Or just written to a bad address.
Difficult to tell without seeing the code.
It's also possible that you have a huge (1MB or so) array on the stack. What does your main() function look like?
ok, here it is the programmers nightmare

At a guess, Map.Tile(6) creates 6 tiles, and you are adding 7.

-no thats the width of a tile in pixels, arguments 2 and 3 in Room() are used to tell the number of tiles )

What line in main() does the debugger point to when you get that exception?
It brings the asm file right away

Ah, I didn't realise it's happening before you even get into main()...

One thing I could suggest is commenting out bits of code until the bug goes away, then you'll be able to track down what caused the bug (It'll be the last bit you commented out). That, and adding some printf() / cout lines will let you see if it's even getting into main().

It's also possible that you just have a crapload of data on the stack in main() - in which case you need to switch to allocating some data elsewhere (I.e. on the heap).
