clean and recompile.

If you still get the error, make sure you''re not using a static library with a different version of the CRT (debug/release, multi/single-threaded).

How appropriate. You fight like a cow.

This sometimes happens if you''ve got your runtime library set different to that of a static library you link with.

but what I dont get is I havent changed the configuration. I pasted some copde in using filebuf and it started

I comment out the filbuf lines and it works just fine.

is filebuf using incompatible debug functions?

Well for anyone curious to this solution

Change the
C++ -> CodeGeneration -> Runtime Libraries from /Md to /Mtd

it worked wow, I think theres additional debugging implanted inside the stream libraries
