Futher to this I now have a stack trace if that helps anyone point me in
the right direction:

I have two handlers, one a response handler and a second an output filter.
If either of these handlers run then they run fine for any number of
requests, if I have both of these handlers I get an untraceable seg fault
with the handlers, this segfault happens on the second request to that
particular child.
If the page is generated from:
* the file system,
* via mod_php or
* mod_rails I don't have a problem
If the page content is generated by mod_perl it works perfectly well for
the first request - but fails for subsequent requests.
[notice] child pid 14475 exit signal Segmentation fault (11)
This appears to be before the page handler executes...
If I turn off the output filter - everything is OK for all requests.
Any suggestions on how I debug this... it makes life so much easier if
I can handle all requests this way (and it seems to be the apache way)
