Does it leave a core file?
What was the configuration change that was made between these two

When this happens, can you use gcore to obtain a core file, or instead
use kill -6 (ABORT) to collect the core file so it can be reviewed with gdb?
When using gdb, please include the output of the stack trace, you can
get this by typing "bt" at the (gdb) prompt.

I've had a "beta" version in development for some time, which should
also reduce the overall cpu usage of the application. I'd like to resolve
this issue and determine if there is enough interest in a minor feature
release. I know i've been slow in development ;)
