This bug went away for a bit, but it seems to have reappeared with recent
versions. There seem to be a couple of problems. The original test case that
I uploaded now crashes with a failure in new, and this trace:

In another example I now get a failure that the debug info generator now
attempts to replace one value with a value of a different type, giving this
