Interesting. There are many buildfarm members reporting that they
use 2.5.37, and we've not seen any issues there. Maybe there's a
platform-specific bug in it? Or those members are really running
vendor-patched versions rather than straight 2.5.37? (Hard to
believe they'd all have the same patch though.)

I also remain suspicious that you were running only one of psqlscan.l and
psqlscanslash.l through your local flex, and using the tarball-provided
output file for the other. We currently use flex 2.6.1 when creating
tarballs. It's not real hard to believe that there was an ABI break
between 2.5.x and 2.6.x ...

Dunno that it's worth any extra trouble to track it down, though.
