The font_options in that surface are definitely corrupt (antialias = 983044,
subpixel_order = 983040, hint_metrics = 45, round_glyph_positions = 3841). If
these number are converted to hex, you get antialias = 0xf0004, subpixel_order
= 0xf0000. That looks a bit similar to the 0xf008.... in snapshot.prev. A
pattern? The snapshot_detach pointer looks fishy, too, but that might just be
unitialized memory (why doesn't _cairo_surface_init() set this to NULL?)

So I guess something evil corrupted everything past the snapshot.next pointer.
As a next step to investigate this, I would propose to run this under valgrind,
but I will just claim that this is not a bug in cairo and close this. Sorry.
