VC++ Internal Compiler Error

That's a very unfortunate thing. Such indications appear once in a while for no apparent reason. Even MSDN recommends to go to the code and play with optimization pragmas there. You have to detect what construct causes this indication and rewrite it somehow. Or you can use a newer version of VC++.

Nope, you're screwed. You've done something that exposed an error in the compiler. Play with optimization settings, #pragmas and fiddling with your code until it works.

And perhaps submit a bug report on connect.microsoft.com

INTERNAL COMPILER ERROR(compiler file file, line number) The compiler cannot generate correct code for a construct, probably due to the combination of an expression and an optimization option. Try removing one or more optimization options and recompiling the function containing the line indicated in the error message. You can probably fix the problem by removing one or more optimization options. To determine which option is at fault, remove options one at a time and recompile until the error message goes away. The options most commonly responsible are /Og, /Oi, and /Oa. Once you determine which option is responsible, you can disable it using the optimize pragma around the function where the error occurs and continue to use the option for the rest of the module.
