I can't say for sure, but the symptoms aren't identical. stage2 gnat1 always
SEGVs in the same way, but SP is below accessible memory, PC is way high in
nowhere land and odd (which isn't allowed), and gdb cannot generate a symbolic
stack trace. stage1 gnat1 does work however, which makes me suspect a
miscompilation. I may have to try a bisection.
