The production VM from the squeak.org download page is from last August and seems to be crashing. Does anyone know where to download the latest 64-bit cog spur linux vm? Thanks.

Fwd: Quick way to run out of memory
by Chris Cunningham 01 Feb '17

01 Feb '17

Forwarded to the list I wanted to send to. ---------- Forwarded message ---------- Date: Fri, Jan 27, 2017 at 9:08 AM do: String new: -1 Yes, it doesn't really run out of memory, it's just a bug in ByteString>>basicNew: (ec == #'insufficient object memory' or: [ec == #'bad argument']) ifTrue: [^self handleFailingBasicNew: sizeRequested]. The VM gives us a nice error code telling us the arguement is bad, and then our code proceeds to assume it is out of memory instead. Bug verified in latest Trunk (as of now), and raw 5.1 image. A proposed fix is in the inbox: http://source.squeak.org/inbox/Kernel-cbc.1054.mcz <http://source.squeak.org/inbox/Kernel-maga.1054.mcz> This fix uses the old " self error: " pattern. If you'd prefer a new error for invalid argument, I would be happy to post a variant for that. Thanks, -cbc
