I downloaded Ian's image/changes bundle named unix-3.10-4.vmm.tar.gz from http://www.squeakvm.org/unix/ and looked into it a bit.
In ObjectMemory biasToGrow it looks like the problem is
biasToGrow | growSize | growSize := growHeadroom*3/2 - (self sizeOfFree: freeBlock) self growObjectMemory: growSize
there are no '.'s after the lines. Shouldn't it look like:
biasToGrow | growSize | growSize := growHeadroom*3/2 - (self sizeOfFree: freeBlock). self growObjectMemory: growSize.
that?
It looks like the slang interpreter/translater must be coughing a bit on what is basically slight invalid syntax, right?
This is http://bugs.squeak.org/view.php?id=6667. The fix was applied to VMMaker-tpr.63. You are probably using sources generated from VMMaker 3.8b6, which is the same as VMMaker-tpr.58, so the sources you are using would not have this fix.
If someone can build a VM using more up to date VMMaker and verify that the problem goes away, that would be good. I suggest using VMMaker-dtl.113 from the VMMaker project on SqueakSource for this. (Note, there is a more recent VMMaker-eem.114 that contains Eliot's updates for block closures, but you may have trouble loading it into some Squeak/Pharo images. The glitch may be sorted out by the time you read this, if not just stick with VMMaker-dtl.113 or earlier for now.)
I guess that next up I have to figure out how to actually run vm maker :-)
Yes :)
