Re: CogVM OpenBSD and the Call Stack
I will attempt as you have said.
I have already done other things and managed to get a successfull build.
I can even load a pharo image successfully!
Thats about it, do anything, and it crashes.
I will do as you say and report back. In the mean time comments are welcome.
Output from crash:

If this is the ucontext.h stuff, afaik nobody has implemented ucontext
for OpenBSD, certainly it's not in-tree.
