[IRCServices] Compiling and Crashing on boot under Solaris 9

I am attempting to use IRC Services 5.0.19.
The IRCD is Unreal3.2-beta16cvs20030527.
I have successfully been using IRC Services 5.0.16 with this server,
although I had to do similar tinkering as mentioned below to get it to
compile. But since compiled, no problems.
The server is an UltraSPARC 1 (sun4u) running Solaris 9. Compiler is GCC
3.2.2.
First, I had to add a -libs parameter to configure with "-lsocket -lnsl
-lresolv" so that it would find hstrerror() and gethostbyname(). It seems
to figure out that it needs -lsocket on its own, so I probably don't have
to add it myself, but I did just to be sure. It refuses to compile
dynamic modules, but I didn't care enough to try and correct that. I also
had to tell Make to be sure to use bash as the shell, instead of Solaris'
braindead /bin/sh by adding a SHELL=/usr/local/bin/bash parameter to the
make command. After that it compiles fine. It still complains that it
cannot find strtok, although this isn't fatal. Solaris does seem to have
this function, however. Here is the relevant snippet from the
configure.log when it attempts to locate strtok:
--
check_strtok : >>> gcc -O2 -fno-strict-aliasing conf-tmp/test.c
-lsocket -lsocket -lnsl -lresolv -ldl -o conf-tmp/test
conf-tmp/test.c: In function `main':

conf-tmp/test.c:22: warning: comparison between pointer and integer
check_strtok : *** Command failed (exit code 1)
check_strtok : didn't find strtok
--
While I'm at it, I might as well clip out the section of log of its
attempt to use dynamic modules. But as advertised, things have worked
fine in the past without dynamic modules:
--
check_shared : found dlfcn.h in /usr/include
check_shared : testing dlfcn method
check_shared : >>> gcc -O2 -fno-strict-aliasing -lsocket -lsocket -lnsl
-lresolv -ldl conf-tmp/test-dlopen.c -o conf-tmp/test
check_shared : dlopen() found (no libs)
check_shared : >>> gcc -rdynamic -O2 -fno-strict-aliasing -lsocket
-lsocket -lnsl -lresolv -ldl conf-tmp/test-dlopen.c -o conf-tmp/test
gcc: unrecognized option `-rdynamic'
check_shared : -rdynamic works
check_shared : >>> gcc -shared -O2 -fno-strict-aliasing -lsocket
-lsocket -lnsl -lresolv -ldl conf-tmp/test-lib.c -o conf-tmp/test-lib.so

The crash occurs on starting services whenever there are database files
present. It starts successfully the first time ever, when no databases
yet exist.
I have attempted two scenarios. I will include the verbose log entries
and the backtrace from gdb for both circumstances.
SCENARIO 1. IRC Services was already started with no database files
present, so that it created blank files. Services is gracefully shut down
with SIGTERM (leaving new db files behind), and then restarted. It
segmentation faults and dumps core.

SCENARIO 2. IRC Services is started with the database files that have
been correctly working under version 5.0.16. This time, it reports a bus
error upon booting, and coredumps. The database files are pretty small
because it's a private server with only a few years -- 3 nicks, no
channels registered, and some logon news.
