Gratuitous default recipient...

If there is a verbose dump option or other diagnostic efforts that will help, I will do my best to run them and report the results.  I am fairly certain the vm is 'Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.54]' (can verify later today), but this happened with an earlier Cog one-click too.  There is something about the machine (UUID again?) that is different.  I do not have root access to it, but I can get to a terminal.  Ubuntu 10.10.

Mariano,

I first identified this problem/opportunity a while ago.  At the time, there was no log - the vm just died.  I can sniff around again as there might be one this time.  My question at the time was whether there was something that I could enable to perhaps get more info.

The output from the vm is, and I quote<g> "Segmentation fault".  There is no other output.  Perhaps it does not get far enough to have a call stack??

Bill

also...shouldn't be a crash/dump file somewhere?

can you write the output of the console where you invoke the VM into a file ?   (using > to redirect)

Cheers

Hello all,

I have an account on an Ubuntu terminal server (at least I think that's what it would be called) running 10.10.  The Cog one-click image crashes with "Segmentation fault" (if run from a terminal); the legacy VM seems to run the image nicely on the box.  Any ideas?  I will happily collect any facts that will be of help, but I need some
direction.

Bill
