I do not know. All I see is that memory usage goes from 800k to 9700k
and then ilrun gets killed by Linux VM (according to kernel log) and
errors reported earlier are printed out. The test program is just a
simple hello world, that runs on my PC just OK. I will try to port libgc
and then we will see if gc was the problem.

I was looking just for this kind of information. Thank you.
