Description Maciej (Matthew) Piechotka 2014-08-16 22:48:09 UTC 
Code:

[CCode (array_length = false, array_null_terminated = true)]
internal uint[]? sizes;
...
sizes += 0;

Results in assertion error:

ERROR:valaccodearraymodule.c:1105:vala_ccode_array_module_real_get_array_length_cvalue: assertion failed: (size != null && size.size >= dim)

(Probably dynamic guess of length and assumption that size == length or just erroring out would be better).
Comment 1 Maciej (Matthew) Piechotka 2014-08-16 22:54:52 UTC 
For that matter following code is also running into similar problem:

[CCode (array_length = false, array_null_terminated = true)]
internal uint[]? sizes;
// ...
var tmp = foo();
tmp += 0
sizes = (owned)tmp;
// Or sizes = tmp;

This makes GLib.OptionArg default arguments awkward to use.

Ups. Sorry - I had the same problem in the same file in different place.
