The production VM released with Squeak 5.1.

    5.0-201608171728  Sun Sep 25 16:02:24 UTC 2016 gcc 4.6.3
[Production Spur VM]

It's been a few months since I tried the most recent VM.  All the
newer ones I'd ever tried since the GC rewrite would crash more often
than I could bear.

I run this same code base and VM to support my own code repository as
a local daemontools service.  It doesn't have the volume
source.squeak.org has, but it has been stable for me.
