Well, I'd like not to do another RC, so I'll hold the larger patch for
8.2.
We still need a test to confirm it fixes Jim's problem though.
Jim, if you like you can test the second proposed patch instead of
that off-the-cuff line swapping. However, either one will need to
be run with Asserts on in order to have any confidence that the problem
is fixed. If performance is an issue, most of the performance hit is
probably coming from memory context checking, so what I'd suggest you
do is comment out these two #defines in src/include/pg_config_manual.h:
#define CLOBBER_FREED_MEMORY
#define MEMORY_CONTEXT_CHECKING
That should let you build with --enable-cassert and not take quite
so much speed hit.
