Fatal error: TSC error

Unfortunately, my attempts to extract a minimal example was failed. I will continue my attempts, but maybe someone of you already knows what could be wrong.

tsc 05fd2e9f (master)

The same code successfully compiles on tsc 1.3.

[s-panferov]

Code to reproduce:

module schema {

    export function createValidator(schema: any): <T>(data: T) => T {
        return <T>(data: T) => {
            return data;
        }
    }

}

Compile with:

tsc --module 'commonjs' test1.ts -d

I think that error is somewhere near #1122

@s-panferov, fix should be in main, can you give it a try. thanks!
