Not sure if I want to add to the blocker list at this time, but I'm curious to hear if someone else has seen this? For some time I've experienced random crashes on OS X (PPC only so far) during startup of Roxen:

A disassembly of F_ARROW follows below, and F_ARROW + 100 equals 0x1652c, i.e. the _index_no_free call. (Disregard the 0x1654c address in the trace earlier since this is a slightly newer build.)
