Hi,

it was found by automatic rebuilding of Debian archive that ruby thread_safe library segfaults with ruby2.0:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=735861

Could you please take a look at that?

I can easily reproduce the bug with ruby2.0:

/tmp/buildd/ruby-thread-safe-0.1.0/debian/ruby-thread-safe/usr/lib/ruby/vendor_ruby/thread_safe/non_concurrent_cache_backend.rb:10: [BUG] Segmentation fault

Hi,

I was optimistic because I couldn't reproduce this bug immediately, but after running the testsuite about 10 times on Debian sid, with ruby 2.0.0p384, I got the following backtrace:

I am attempting to reproduce this locally on OS X, and if that fails I'll try to test on a system more similar to yours. No leads, no theories.

It also occurs to me this could be a Ruby 2.0 bug. Could you try to report it to ruby core and see if maybe they have a theory as to what is happening?

Ok, I realized that thread_safe doesn't even include an extension for MRI, so this is almost certainly an MRI issue. Closing in favor of https://bugs.ruby-lang.org/issues/9649 (please comment and follow that issue).

@headius sorry, should have looked into this. You are right - on MRI thread_safe is always a pure ruby business, no c-exts are involved (not even the atomic gem, as it is only ever used when running on Rubinius).
