I've actually had an ungodly metric ton of ruby segfaults in the past month or so, and almost never before that. At least one of them has definitely been GC-related - see "therubyracer is not thread safe" for one problem I've been running into. You also have to use PassengerSpawnMethod conservative to avoid GC-related failures in passenger with rails 3.1. I'm not sure if those are both related to this or not, but I've had drastically more segfaults lately than in my past 6 years of ruby programming. It's getting pretty bad imo.
