Core dump in regression tests.

If anyone has been watching my trials and tribulations building
and running the latest CVS snapshot under S/Linux on a SUN
SPARCstation IPX.

The latest position is:-

If I compile with optimization turned off (-O0 instead of -O2)
I get an almost clean run of the regressin tests. Only the
"create_function" tests fail unexpectedly.

pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally before or while
processing the request.
We have lost the connection to the backend, so further processing is impossible.

Has anyone else seen anything similar?

PS: Bruce, I still need to find which file breaks an -O2 compile but
will spend some time playing over this long weekend.
