checking on buildfarm member thrush

I'm trying to determine why thrush has been failing on PG CVS HEAD for
the past few days.  Could you try running the attached program on that
machine, and see what it prints?  I suspect it will dump core :-(

Note: you might need to use -D_GNU_SOURCE to get it to compile at all.
