Linker Tools Warning LNK4020

a type record in 'file' is corrupted; some symbols and types may not be accessible from the debugger

The Visual C++ compiler may have produced debugging information that is incorrect, and the resulting debugging information for the executable may be incomplete or incorrect. Try recompiling the .pdb application with the Visual C++ 2003 (or later) compiler.

If the problem persists, contact Microsoft Product Support Services.
