3 threads and trace shows one executing.

The address of the the environment is erased from the stack
incorrectly (methinks) and the environment does not exist
after it is erased. and the Lua code fails.

I think (maybe) I can create a test program for this case that will fail,
would this be a better approach?

Will do.
The problem is with the environment and the stack.

Sorry about this I have *never* looked at the GC code before (or
had a reason too) and I am fumbling my way around here.
