Subject: [sup-talk] Stack overflow in regexp matcher
Message-ID: <92457f310908030116k146a901aleee95a09db907d97@mail.gmail.com>

Hi there

I'm trying to run sup 0.8.1 on Mac OS 10.5.6, Ruby 1.8.6 but sup-sync
is repeatedly dying:

MC-S001930:~ draytm01$ sup-sync -c

	from /usr/bin/sup-sync:19:in `load'

This error seems to have cropped up in other software so I suspect
it's a problem with Ruby, not sup. Anyone able to confirm this?

Cheers,

Mark
