I've also noticed the same problem when using the james gem on Lion. I'm not sure if I logged a bug (this was prior to Lion's official release). It also wouldn't be the only GC warning that MacRuby has on Lion right now.

Could you log a bug against MacRuby for this issue?

Thanks,
Mark

I get this new warning message running my MacRuby app on Lion:

MacDriverLog(262,0x104f0e000) malloc: *** auto malloc[262]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug.

This doesn't crash my app. Can I safely ignore this warning?

Thanks,
Bob Rice
