Comment 1 Andreas Brauchli 2009-01-16 15:56:39 UTC 
multidimensional arrays are declared differently than in C.. maybe the parser should warn about this usage..

this works fine:

public class test {
    public static void main () {
        string [,] abc = new string [1,2];
        string [,] def = abc;
    }
}
Comment 2 Michael 'Mickey' Lauer 2009-10-08 12:04:58 UTC 
Meanwhile, the situation got worse with regards to the original issue. Vala no longer emits an error, but CRITICALs:

** (valac:13608): CRITICAL **: vala_ccode_array_module_real_get_array_length_cexpression: assertion `array_expr != NULL' failed

** (valac:13608): CRITICAL **: vala_ccode_function_call_add_argument: assertion `expr != NULL' failed
Compilation succeeded - 1 warning(s)

    Report error when trying to use stacked arrays
    
    Stacked array support was never completed. Report an error instead of
    generating incorrect C code.
