Memory issue

I am getting this error - could not reproduce on 1.9.2-p290 - should I report to you or Ruby?

[[BUG] rb_gc_mark(): unknown data type 0x0(0x7f3ef9855218) non object suggests it is a Ruby VM problem.

[michaelklishin]

By the way, what patch level is this? amq-protocol is tested against most recent releases of nearly every Ruby out there

[marekjelen]

Thanks .... will report there.

It's the 1.9.3 provided by RVM.

When I have to use CRuby, this is what I use these days. I haven't seen GC issues. If you are using C extensions (including those in the standard library), this may cause side effects on GC if those extensions are not taking special care to use GC barriers. So please mention them in your report to Ruby core team.
