Ah --- that's why it links, anyway. As for "works", I suspect that the
answer is that anole has a vsnprintf that returns -1 on buffer overrun.
vasprintf and then psprintf will interpret that as "out of memory",
resulting in the observed behavior. It'd be interesting to see the stack
trace from that error, though, just to confirm this theory.
