>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 *[][]'.

State-Changed-From-To: analyzed->closed
State-Changed-By: paolo
State-Changed-When: Wed Jan  1 12:41:58 2003
State-Changed-Why:
    Cannot be reproduced with 3.2.1, 3.3 pre, mainline.
    Mainline, f.i., issues:
    5447.cc:1: error: multidimensional array must have bounds for all dimensions
       except the first
    5447.cc:7: error: declaration of `arr' as multidimensional array must have
       bounds for all dimensions except the first

State-Changed-From-To: open->analyzed
State-Changed-By: rodrigc
State-Changed-When: Mon Jan 21 16:25:00 2002
State-Changed-Why:
    segfault reproduced with gcc 3.0.3.
    
    With gcc 3.1 in CVS, no segfault, but the following compilation error, when compiled with g++:
    seg3.cpp:2: multidimensional array must have bounds for all dimensions except
       the first
    seg3.cpp:8: declaration of `arr' as multidimensional array must have bounds for
       all dimensions except the first
    
    Putting it in a seg3.c file and compiling with gcc -pedantic
    yields warnings:
    seg3.c:2: warning: array type has incomplete element type
    seg3.c:8: warning: array type has incomplete element type
