>Description:
Causes G++ to segfault:
seg3.cpp:1: Internal error: Segmentation fault
>How-To-Repeat:
Create a file named 'something.cpp' (it must be a C++ extension, not a C one). Fill the file with this code:

// ---
void someFunc(char *[][], int, int);

int main(void) {
    return 0;
}

void someFunc(char *arr[][], int alpha, int beta) {
}
// ---

Simply compile it using (for example): g++ -o abc something.cpp. If you use the gcc frontend to g++ it will segfault also. It will not segfault if it is a .c file.
>Fix:
Use 'char ***' instead of 'char *[][]'. Or use 'char *[][num]' instead of 'char *[][]'.
