Could be this:

It's fixed in patch 124861-11 which came out Feb 23, 2009. Is this
patch missing on both gothic-moth and codlin-moth?
I suppose it's possible to have a configure test to check for whether
this patch is present but I'm not sure how much it's worthwhile given
that it'll only help people who happen to recompile their 8.2 server
after the next Postgres patch. And I'm not sure we can check for
patches without assuming the CC is the OS-shipped cc. Does cc itself
have an option to list which patches it has applied to it?
