Thanks for checking ECL out. Regarding the failure in your tests there
are a few points worth noticing

- The recursive version will fail in the interpreter due to interpreter
stack overflow.
- The recursive version in the compiler, in a linux machine (Debian),
works ok.
- The following interpreted version should also work
        (defun fac (x &aux (y 1)) (dotimes (i x) (setq y (* y (1+ i))))
y)

Please make sure that the code has been properly updated (For instance,
you should find a couple of GC_malloc_atomic_ in alloc_2.d) and that you
made a fresh new build of ECL (otherwise the core library will not get
updated).
