Please describe the problem:
When pointing an array-of-arrays to another array-of-arrays, valac CRITICAL errors are logged and gdb fails on the .c files.  It appears the generated .c code is not supplying enough parameters to a generated helper function.

Steps to reproduce:
I'm using this source:

void main(string[] args) {
    int[][] foo = new int[3][4];
    int[][] bar = foo;
    
    stdout.printf("%d", bar.length);
}

Actual results:
valac produces this:

** (valac:22089): CRITICAL **: vala_ccode_array_module_real_get_array_length_cexpression: assertion `array_expr != NULL' failed

** (valac:22089): CRITICAL **: vala_ccode_function_call_add_argument: assertion `expr != NULL' failed
foo.c: In function ‘_vala_array_dup1’:
foo.c:25: error: too few arguments to function ‘_vala_array_dup2’
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)


Expected results:
Compile without error.

Does this happen every time?
Yes.
