I have a program that does a:
DECLARE getsitescursor CURSOR FOR select...
I ^C'd it and it didn't properly shut down the channel to
postgresql and I got this crash:

things go to pot here:
387 {
388 AllocChunk chunk;
389
390 /* AssertArg(AllocSetIsValid(set)); */
391 /* AssertArg(AllocPointerIsValid(pointer)); */
392 AssertArg(AllocSetContains(set, pointer));
393
394 chunk = AllocPointerGetChunk(pointer);
395
396 #ifdef CLOBBER_FREED_MEMORY
(gdb) print *set
$2 = {blocks = 0x0, freelist = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}}
(gdb) print pointer
$3 = 0x84e0018 "<hashtable 1>"
These sources are the current CVS sources with the exception of
some removed files by Marc.
Is there any more information I can provide?
