========================================================================
After looking into this problem, I found the compiler thought that sizeof(void *) and sizeof(const void *) are of different sizes.

I'm really confused.

The problem seems to be in glib, I'll have a look.
Comment 2 valentin 2014-03-11 14:02:46 UTC 
Indeed it's a glib bug not a gtk+ one.
If gsize is unsigned long then probably gssize should be signed long and not signed int (see glibconfig.h). You can hard code gssize until a patch is provided.
