Summary:                    Crash in ast_queue_frame
Description: 
We've been getting this crash randomly with a frequency of one every day or
two (sometimes, two in one day). We first saw this problem in 1.4.6, and we
switched to 1.4.11, then 1.4.12.1 to see if the problem might have been
fixed. On 1.4.12.1, we still have the problem.

This appears to be related to an issue,
http://bugs.digium.com/view.php?id=0009694, that was reported in
May, then closed in August due to a lack of further information. That
reporter claims disabling compiler optimizations made his problem go away,
but that sounds like he just changed the timing of his race condition.

What further information can I provide?
