I've got a backtrace. I've realised that it does in fact crash on particular
jobs, rather than randomly after a load of them. Any fixes or workarounds are
immensely welcome, this is causing an untold amount of pain for me.
Program terminated with signal 6, Aborted.

Sure, I'll give it a go when I get a chance, probably later this week.

Could you pls try to get a decent GDB backtrace?
See instructions here: https://bugs.php.net/bugs-generating-backtrace.php

I'm sorry but I have no idea what in my >20k line codebase is triggering this,
and thus can't give you an example script.
------------------------------------------------------------------------
[2012-05-13 14:46:37] [email protected]
Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
