Tom very kindly stepped in and had a poke around with a debugger (and
had to use -- eek -- adb because there was some sort of argument
between gdb compiled as 64 bit and Solaris), and discovered that
vsnprintf was doing something nasty.
Turns out, according to the GNU autoconf pages (at
<http://www.dis.com/gnu/autoconf/autoconf_45.html#SEC45>), that
vsnprintf overruns the buffer sometimes.
The answer is to edit src/backend/port/Makefile and add "snprintf.o"
to OBJS. Postgres includes its own implementation for platforms that
don't have it.
Thanks to Tom Lane.
