Internal Compiler Error : Unexpected token ILLEGAL, preprocessor

[ghost]

i'm working on "library_signals.js",
but I think that this problem can also occur elsewhere.

if i insert 'tab' compiler crushes
about preprocessor directive

does not work :

        sigaction: function(signum, act, oldact) 
        {
        //int sigaction(int signum, const struct sigaction *act, struct sigaction *oldact);
        #if ASSERTIONS
            signal__deps.printErr('Calling stub instead of sigaction()');
        #endif
            return 0;
        },

work :

    sigaction: function(signum, act, oldact) 
    {
    //int sigaction(int signum, const struct sigaction *act, struct sigaction *oldact);
#if ASSERTIONS
    signal__deps.printErr('Calling stub instead of sigaction()');
#endif
        return 0;
    },

output error message

I can't reproduce this. I put some tabs into src/library.js and I don't see an error.

let me do others tests
