unexpected segmentation fault

[simpatico_qa]

The faulty code for the project is in
trunk - sscompiler - Project Hosting on Google Code
It includes a makefile.
if you run: ssCompiler.out and then type int main(int c){} it will give a segmentation fault.

If you try the following main, it will work correctly (see output).
The unexpected thing is that when the above project fails is in addFunction("int", NULL, "foo") (with the same hard-coded parameters).

Unfortunately the debugger couldn't help me with the yacc project, while in the main below, everything works!

Immensly grateful if someone could try out my claims, and point me out. I recall there where compiler advocates on board, hopefully yacc experts too.

int main(int argc, char** argv) {

/*
    list* fList = newFunct("int",NULL, "foo");
*/
    addFunction("int", NULL, "foo");
/*
    addFunction("int", NULL, "bar");
*/
    printFList(fList);
    assert (findFunc(fList, "foo"));
/*
    assert (findFunc(fList, "bar"));
*/

    return (EXIT_SUCCESS);
}

int main(int c){}

The standard says the construct for main is:

int main(void);

OR

int main(int argc, char **argv);

Or any char ** type identifier (that'd be char *argv[] and char argv[][])

[simpatico_qa]

Then try

 void foo(int b){}

. It was just any method definition with an argument.

I guess I found the solution. Still to verify, though.

The standard says the construct for main is:

int main(void);

OR

int main(int argc, char **argv);

Or any char ** type identifier (that'd be char *argv[] and char argv[][])

It also allows for "some other implementation defined manner" as well. So while not portable, you could write a compiler to allow it to take whatever you need in your environment.


Quzah.

the issue I'm having is that in the yacc.y file I define a global list fList = NULL; I then want addFunction to add to it. The problem is that when it receives fList, it isn't NULL, although I set it so in the main() of yacc, and right in the declaration line. If I set it to NULL in the line before addFunction call in yacc.y, it works. Any suggestions?

Is it at the end of yacc grammar?
