It compiles fine, but upon further inspection, I believe it may be a bug in cairo that the new code is exposing. Here is output when running the car_smash.swf file provided in the testsuite: gnash: cairo-bentley-ottmann.c:754: _cairo_bo_event_queue_init: Assertion `_cairo_bo_point32_compare (&edges[i].top, &edges[i].bottom) < 0' failed. Aborted Unfortunatly, that output is not consistent. Sometimes it crashes with that output, and others it runs but nothing is displayed, such as with test.swf. Also, here is a backtrace of the crash: (gdb) run ./car_smash.swf Starting program: /usr/bin/gnash ./car_smash.swf [Thread debugging using libthread_db enabled] [New Thread 47131925121040 (LWP 24034)] [New Thread 1082132816 (LWP 24525)] gnash: cairo-bentley-ottmann.c:754: _cairo_bo_event_queue_init: Assertion `_cairo_bo_point32_compare (&edges[i].top, &edges[i].bottom) < 0' failed.
