Viewing the PDF spec in evince, it got into an infinite loop. The backtrace looked like this: (gdb) bt #0 0x0000003822c1b484 in _clip_paths_are_rectilinear (clip=0x7fffb5b6cd40, boxes=0x7fffb5b6cb50, count=0x7fffb5b6cb5c) at cairo-clip.c:517 #1 _cairo_clip_path_to_boxes (clip=0x7fffb5b6cd40, boxes=0x7fffb5b6cb50, count=0x7fffb5b6cb5c) at cairo-clip.c:853 #2 _cairo_clip_get_boxes (clip=0x7fffb5b6cd40, boxes=0x7fffb5b6cb50, count=0x7fffb5b6cb5c) at cairo-clip.c:1320 #3 0x0000003822c1cf45 in _cairo_clip_to_boxes (clip=0x7fffb5b6cba0, extents=0x7fffb5b6cae0, boxes=0x7fffb5b6cb50, num_boxes= 0x7fffb5b6cb5c) at cairo-clip.c:1388 #4 0x0000003822c4b084 in _cairo_surface_fallback_fill (surface=0x184d810, op=CAIRO_OPERATOR_OVER, source=0x7fffb5b6cc20, path= 0x3822eab158, fill_rule=CAIRO_FILL_RULE_WINDING, tolerance=0.10000000000000001, antialias=CAIRO_ANTIALIAS_DEFAULT, clip= 0x7fffb5b6cd40) at cairo-surface-fallback.c:1154 #5 0x0000003822c483aa in _cairo_surface_fill (surface=0x184d810, op=CAIRO_OPERATOR_OVER, source=0x7fffb5b6cc20, path=0x3822eab158, fill_rule=CAIRO_FILL_RULE_WINDING, tolerance=0.10000000000000001, antialias=CAIRO_ANTIALIAS_DEFAULT, clip=0x7fffb5b6cd40) at cairo-surface.c:2163 #6 0x0000003822c219aa in _cairo_gstate_fill (gstate=0x3822eaae70, path=0x3822eab158) at cairo-gstate.c:1283 #7 0x0000003822c18c05 in cairo_fill_preserve (cr=0x3822eaae40) at cairo.c:2277 #8 0x0000003822c18c41 in cairo_fill (cr=0x3822eaae40) at cairo.c:2253 #9 0x00007f428892d9e0 in ??
