I see the problematic face always has face ID of 18, and the 'used'
field is always 15 when the segfault strikes. So I guess the next
step is to make the breakpoint in cache_face conditional on i being
18, and then see whether c->used is set to 19 during that call to
cache_face. If it does, then a watchpoint (by location) on c->used
should show which code makes the value smaller.
