I compiled gstreamer (1.3.1/1.3.2) with MinGW 4.8.2 (mingw-w64
i686-posix-dwarf-rev3) and gstreamer-win-1.2.4.1(gstreamer file removed,
dependency such as glib reserved ) and try to use gl plugin , 
gst-launch-1.0 videotestsrc ! glimagesink 
but window does not create

,with GST_DEBUG, log shows last here:

.c:944:_init_convert: Initializing color conversion from I420 to RGBA

gdb shows backtrace as follows:

I also compiled gst-plugins-gl with gstreamer-win-1.2.4.1, everything works.
