Created attachment 132862 gdb backtrace of the crash
This is a crash happening on a Fedora 26, with an AMD card, while running eog on a large file. It seems that the case where source, mask and source_pixmap are null (from the definition of the macro COMPOSITE_REGION) is not handled properly in function glamor_composite_clipped_region().
