Very interesting - my crash seems to happen during WordDBPage::Compress
I'm using htdig-3.2.0b4-110401 but I've made a few customizations for use
on our site - mostly to htsearch to enhance search results displays.......I
have considered upgrading the snapshot but the size of the job has stopped me
- I'll have to port my customizations to the new snapshot, etc......
However, I have gone back to creating one master database with everything
in it and using "restricts" to control the results......hence, merging is not
required right now.......if I need to merge in the future I will likely
upgrade my snapshot and try again :-)
Thanks to for your help!
Cheers,
Jonathan.

I build all 3 separately then I call htmerge 2 times with the -m
option to
merge the 2 smaller ones into the larger one. Every time I try that the
merges fail. I also get a core dump......not sure what is
happening.....
to the newest snapshot, if that is possible and you haven't already
done so. If that doesn't solve the problem, I would suggest using gdb
(or whatever debugger you have available) to grab a backtrace from the
core file and submitting that along with any other info you think might
be useful.
I did a quick test with the htdig-3.2.0b4-20021013 that I have
installed on one of my systems, and I did encounter a crash. The
backtrace is included below. Can you tell if your setup is crashing in
the same place?
