Segfault in pgsql, Sparc Solaris 2.7, Postgresql 7.1.1

Howdy,

I'm getting a segfault from psql when a createdb is attempted.
Postgresql is configured with:
./configure --prefix=/opt/pgsql --enable-syslog
and seems to compile without trouble (gcc 2.95.2), but fails
during the createdb stage of the regressions tests.

Installing and attempting to do the relevant bit of createdb
from the command line:
======
$ gdb /opt/pgsql/bin/psql
GNU gdb 4.18
<snip banner>
(gdb) set args -d template1 -c "CREATE DATABASE \"paulmtest\""
(gdb) run
Starting program: /opt/pgsql/bin/psql -d template1 -c "CREATE DATABASE
\"paulmtest\""
CREATE DATABASE

Program received signal SIGSEGV, Segmentation fault.
0xff363b60 in __do_global_dtors_aux () from /opt/pgsql/lib/libpq.so.2
(gdb) bt
#0 0xff363b60 in __do_global_dtors_aux () from /opt/pgsql/lib/libpq.so.2
#1 0xff3728d4 in _fini () from /opt/pgsql/lib/libpq.so.2
#2 0xff3ba060 in ?? ()
#3 0xff0a0130 in _exithandle () from /usr/lib/libc.so.1
#4 0xff116964 in exit () from /usr/lib/libc.so.1
======

Any ideas?
