Description Olivier Le Thanh Duong 2011-05-31 20:47:02 UTC 
When compiling from Jhbuild (gnome3.2 moduleset), after encountering and fixing #651514, I get the following errors : (if I use the patch in comment 1)
gstelementfactory.c: In function ‘gst_element_factory_create’:
gstelementfactory.c:397:8: error: dereferencing type-punned pointer will break strict-aliasing rules
gstelementfactory.c:397:8: error: dereferencing type-punned pointer will break strict-aliasing rules

And if I put () around the macro I get the same erros in gstatomicqueue.c:

Why did you file a duplicate bug referencing the one you're duplicating?
Comment 2 Olivier Le Thanh Duong 2011-06-01 08:05:05 UTC 
Because I saw a different error message and didn't understood the technical implications of the other bug so I assumed it was a different issue. Sorry about that
