Greetings,

I've recently started getting a segfault when running our integration test suite against Rails 3.1.12.

The segfault happens very often, so it is easy to reproduce, but complicated to set up. It does not segfault 100% of the time.

I've attached the full crash log and segfault traces. The traces seems to terminate in the view instrumentation block for rendering a template, where it attempts to call ActionView::Base#send .

I have been unable to isolate the issue to a single test; however, one of two particular tests always appears in the ruby backtrace, and the same frames are always at the top of the backtrace (ActionView::Base#send as described above).

Please let me know if you'd like any additional information. I'm happy to help.
