Subject: [ruby-core:49537] How best to debug random ENOENT problem in 1.9.3?

Hi everyone,

I'm randomly getting ENOENTs from what looks like mem-corrupted load paths:

/home/me/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/cust=
om_require.rb:36:in
`require': No such file or directory - /=B2 (Errno::ENOENT)
from
/home/me/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/cust=
om_require.rb:36:in
`require'
from /home/me/.rvm/gems/ruby-1.9.3-p327@global/gems/bundler-1.2.2/lib/bundl=
er/source.rb:1:in
`<top (required)>'

RUBY VERSION: 1.9.3 (2012-11-10 patchlevel 327) [x86_64-linux]

This happens quite randomly. The "/=B2" sometimes is is sometimes a screwed
up home directory path that looks like memory corruption.

What I did:
1. install rvm (stable) from scratch
2. install ruby-1.9.3-p327 using rvm
3. install gems using bundler

I can't think of anything reasonable other than trying ruby-1.9.3-head and
then bisecting... reinstalling rvm+ruby+gems from scratch every time. Or
rebuild a full-debug Ruby.

Didn't want to file a bug report without more info. Any ideas about how to
quickly nail this?

Sorry if it isn't a Ruby core problem. I just want to be 100% sure it isn't
...
