test case

with GLib.Value as GObject property, Vala generates two GValue and returns wrong value (the initialized GValue isn't returned)
Comment 1 Yannick Inizan 2017-03-25 07:20:11 UTC 
vala version : 0.34.7
GLib version 2.52.0
Comment 2 Yannick Inizan 2017-03-25 07:42:06 UTC 
same bug with vala = 0.36.0, where value is unset before being returned.

test case 2

In this test case, the value in static function isn't unset
Comment 4 Rico Tzschichholz 2017-03-25 07:58:27 UTC 
The problem is that due to the implicit GValue conversion the property-accessor must be declared as "owned get".
Property-accessors are by default unowned, so vala needs to throw an error about owned to unowned assignment.
Comment 5 Yannick Inizan 2017-03-25 07:59:58 UTC 
I understand. so I have to rewrite my code. thanks :)
Comment 6 Rico Tzschichholz 2017-03-25 14:43:40 UTC 
This is a bug after all.

Marking the property-getter as "owned get { ... }" is hardly a rewrite ;)
