OK, I rebuilt PostgreSQL with GCC 3.4 and added -lstdc++ to LDFLAGS. The 
simple test query:
select geomfromtext('');
now gives a much more reasonable answer:

ERROR:  Invalid OGC WKT (too short)

Just waiting for inputfrom our developers if that is what they expected 
to see :)

Thanks for helping to pinpoint the problem. Hopefully we can upgrade to 
FreeBSD 6 soon and leave GCC 2.95 behind forever.
