I saw on the squeak swiki two Squeak Central projects:
http://minnow.cc.gatech.edu/squeak/BlockClosures, and
http://minnow.cc.gatech.edu/squeak/NewCompiledMethodFormat.

Is there any code for these, particularly any SystemTracer code.  I already
have most of the compiler and interpreter re-written using the new
CompiledMethod format and BlockClosures, but I can't test it until I convert
an image using SystemTracer.  I ran the basic SystemTracer that comes with
the latest image.  It finishes creating an image file, but when I start it
up the VM crashes (Exception code: C0000005) in Windows 98.  Has anyone
created a working clone lately?


Tim Rowledge <tim at sumeru.stanford.edu> is widely believed to have written:

I have.

I'm working on this.
