Nope, this was a 64-bit build. It's mysterious to me as well. A bug in
the underlying system is not beyond the bounds of possibility!

I'll run the gnulib parallel tests in a tight loop overnight, in the
same environment, and see if I can make it happen again. If it can, it's
time to figure out how to reproduce it under gdb: I guess running the
gnulib tests in a tight loop and then running this test in a tight loop
under gdb until it dies might work.
