That's pretty old. I'm not even sure I have the ability to easily build 1.5 any
longer (it lack patches from later releases that are probably needed to make it
work with whatever set of libraries and compilers we have now).
I think you're doing the right thing. Do you have the ability to try your test
with 2.0 or master (or even 1.8)? This feels like something long since fixed,
but if it's still broken, I'd sure like to fix it right away.
