Okie dokie! boxes are crashing all over the place today so I finally have some back traces without stuff optimised out.
Here are the details from two of these crashes which occurred on two separate deployments—please let me know if they actually contain actionable information now and I will upload them to the bug.
Thanks folks.

Resending this after the last attempt went into the mail server black hole:Hey Amos
I decided I’m not confident enough in 3.5.HEAD, after last time, to go back into production with it. Going to to do some more local testing first.
That being said, I now have 3.4.12 in production with optimisations disabled and it seems to be doing fine performance and stability-wise. I only managed to capture one crash with optimisations disabled, so far, but it seemed to have some memory-related corruption, unfortunately.
Updates to come over the next few days.On 23 March 2015 at 16:59, Dan Charlesworth <dan@xxxxxxxxxxx> wrote:Hey Amos
