The bug doesn't appear to reproduce if EVALUATE is replaced with an empty function.

I have created a branch (refs/heads/isolate) which reproduces the issue with only 88 lines of code. There are no dependencies on any libraries or low level hackery. This may be a bug in SBCL.

I filed a bug with SBCL. See https://bugs.launchpad.net/sbcl/+bug/1635096
