It's hard to guess at what caused the core dump without being able to
run the debugger on it. There was a bug in the metaphone fuzzy match
method that caused segmentation faults in 3.1.2 and older, so if you
have metaphone in your search_algorithm attribute try taking it out.
Apart from that, I think the only remaining problems that caused core
dumps in htsearch were an empty search word list and database corruption.
The former occurs when you use the keywords input parameter, but leave
"words" empty, which doesn't appear to be the case for you. The latter
can usually be corrected by rebuilding your database from scratch,
so you may want to try that.
Mind you, we haven't had a lot of testing on Digital Unix, so I wouldn't
rule out platform-specific problems, but then you'd think it would affect
other clients of your ISP as well.

112K does seem awfully small, but them I'm not familiar with Digital Unix.
Differences in optimization, stripping the binary after linking, and
using shared libraries vs static linking can all affect the size of the
binary, so a reduction in size like this is not necessarily unusual.
What I find surprising is that this is about a third of the size of the
equivalent Red Hat Linux/Intel 4.2 libc5 binary of htsearch. Either this
is extremely tight code, or the binary is truncated. Is this copy for
your use only, or do other users share the same copy of the binary.
You may want to check with your ISP to make sure your copy is intact
and complete, or try reinstalling again.
Incidentally, the current stable release is 3.1.5, which came out over a
year ago. 3.1.2 is about 2 years old, and has a somewhat nasty security
hole in it. Maybe you can convince your ISP to upgrade.
The talk about the newer htsearch being faster was probably in reference
to the 3.2.0b3 beta release.
