Yes, this bug appears to be present in 1.06 as well. If you change the runtime heapsize, it sometimes manifests as a segmentation fault, other times as a (correct) out-of-heap error. This suggests a garbage collector problem. I also have a couple of other example programs displaying odd behaviour of this nature. As a workaround, you can set the heapsize to one which appears to work. Unfortunately, you'll have to do that by trial and error - for some programs a smaller heap is best, for others, a larger heap. Meanwhile, I'm searching for a proper fix. Regards, Malcolm
