Mod_proxy_html segfaults

Hi,

I have some problems with mod_proxy_html on Solaris.

On Solaris 9 (Apache 2.2.4 and Apache 2.0.55,
libxml2-2.6.30)  , I've
encountered the following problem with mod_proxy_html. I
have
downloaded, built and installed the mod_proxy_html release (
it seems to
be released 2007-07-31). It should contain a bug fix against
segfaults
(2007-06-17) but apparently I have run in to this anyway.

I also reterieved the latest version (2007-10-04) from svn ,
from the
log it says :

"Refuse to run (and segfault) with no links configured
and nothing to
do"

I don't know if the latest svn-version could address my
problem nor the
status of the svn-version , it is propably the developer
version and I
should rely on the official release (2007-07-31). 

I have tried to debug this but without success. Truss gives
me nothing
to go on and the logs aren't very helpful. But it seems
consistent
enough. Fortunately I am not forced to use mod_proxy_html,
but I would
like to clean up my build if possible.

Regards,
Anders
