Colin,

Thank you for doing this!

Your message to vm-dev was initially blocked due to message size, but I
re-sent it to the list and put a copy of your crash-image.zip here:

It's a holiday week in the US so you may not get an immediate response on
the crash issue.

The main thing is that you have it working in 4.6 (yay!) so we now have a
working baseline for image segments with Environments, and whatever issues
are appearing in 5.0/trunk can be much more easily understood and addressed.

I am not certain, but I expect we will want to merge them back into the
squeak46 repository, and possibly also consider doing a maintenance release
to the 4.6 image. Having an up to date image with working image segments
seems like a pretty big deal to me :-)
