Hi,

I did some effort into getting this working. but first you could try to use
an
or-map to get what you want in stead if compiling everything into code. but
it's probably
faster what you are doing.

Anyway in vm.c I changed the
#define VM_DEFAULT_STACK_SIZE (64 * 1024)

to
#define VM_DEFAULT_STACK_SIZE (64 * 1024 * 64)

and recompiled!

Then I can compile to tree-il. Compiling all the way does not work well,
But if you enter
scheme@(guile-user)> (compile program #:to 'value #:opts '(#:partial-eval?
#f #:cse? #f))  ;;NO OPTIMIZATION PASSES

It will compile to.

$7 = #<procedure 3708400 (proto server-port client-zone server-zone
signature-id)>


In all this emphasizes what I said in earlier and I would still ask for a
sane way to change the stack size for guile
and document it well.

Cheers!
/Stefan
