Sample program

If I have a function which returns a null-terminated array as an out parameter (e.g. the alternates parameter of g_str_tokenize_and_fold()), the length of the returned array is calculated as -1, rather than having _vala_array_length() called on it.

Sample program attached. Both assertions should pass — for me, with Vala 0.27.1.7-1a9de, the second assertion fails.

    Fixes bug 743877

This problem has been fixed in the unstable development version. The fix will be available in the next major software release. You may need to upgrade your Linux distribution to obtain that newer version.
