It's not completely without precedent, on the Z-80:

The problem is much smaller than that, actually.

For your weekend entertainment, here's a bit of parrot assembler for the
adventurous to play with. To get the code, just head to:
http://geeksalad.org/basic and download the latest tar bundle you
find. The README.basic file included in the tar bundle is listed after this.

Some patches committed last evening nearly took care of the problem -- at
least they appeared to make my small example appear to
work. Sometimes. :) Here's a slightly larger but better example that so
far hasn't failed to show the stack corruption problem anywhere:
TOKENIZER:
set S
(p6i cc'd)
Okay, I've got this down to a dozen lines. I'm using a build pulled from
CVS two hours ago. In case what's going on here isn't obvious, I'm
shifting the first character off of S2 and putting it on the stack until S2
is finally exhausted. It's a boiled down version of my tokenizer

What follows are a collection of PASM routines that I've been using while
tinkering with the assembler and parrot. Feel free to use, mutilate, add
to, discuss, mock. They are:
a tokenizer
isalpha and isspace
stack routines: sort, replace, peek, reverse

I'm in the midst of writing some routines to debug pasm code, and one of
the things I dearly want is a "stack dump" routine. I can *almost* code
this in pasm, except I'm missing one last component: a way to tell the
depth of the stack without causing the runtime to bail.
