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.
