Oh… 

I have no idea. Maybe something related to Nativeboost. 

If you use a pre-Spur image and VM you will not have any problem.

I am really wondering whether having Spur for Pharo 5 is such a good idea.

I don't know. Before running faster, I need to be able to run something. Or at least some key packages like Roassal2 :)

Today I spent all day trying to run Pharo 5 + Roassal2 in Windows 8.1 without hangs. Not working yet, even with stack VM http://get.pharo.org/50+vm

The 0-byte crash.dmp is not helping at all. This is dissapointing because I was not planning to debug the VM, or consider moving to Linux.

Anyway, is there a way to get a pharo 5 pre-spur image and VM now?

Guys

This is christmax. We worked 8 h a day last week teaching. We travel from the other part of the world.
Why do you update the bleeding Pharo 50 and after complain?
