Subject: [ruby-core:69942] [Ruby trunk - Bug #10968] [BUG] object allocation during garbage collection phase in /opt/rubies/ruby-2.2.1/lib/ruby/2.2.0/openssl/ssl.rb:177

Issue #10968 has been updated by Steve Torrence.

File crash_thin.txt added

I have recently experienced two crashes (stack traces attached) that appear similar to Mr. Rigart's. Both appear to involve creation of a new array in methods called indirectly from the block passed to Thread.new. 

Both occurred when running cucumber tests in a rails app. Unfortunately I haven't figured out how to reproduce them.

crash_webrick.txt happened under rails 4.1.6 when using webrick as the http server for the tests.

crash_thin.txt happened under rails 4.1.11 when using thin as the http server for the tests.
