Thanks!

Do you speak any assembler?  I'm failing now here:

0x0000641e <my_malloc+134>:     call   0x2e5b <make_cons>
0x00006423 <my_malloc+139>:     mov    %eax,%edx
0x00006425 <my_malloc+141>:     lea    0x233caf(%ebx),%eax
0x0000642b <my_malloc+147>:     mov    (%eax),%eax          
0x0000642d <my_malloc+149>:     mov    %edx,(%eax)          <-------
0x0000642f <my_malloc+151>:     lea    0x233caf(%ebx),%eax
0x00006435 <my_malloc+157>:     mov    (%eax),%eax
0x00006437 <my_malloc+159>:     mov    (%eax),%esi
0x00006439 <my_malloc+161>:     mov    0x8(%ebp),%eax
0x0000643c <my_malloc+164>:     mov    %eax,(%esp)
0x0000643f <my_malloc+167>:     call   0xa79a4 <alloc_simple_string>


on C code

        malloc_list = make_cons(Cnil, malloc_list);

        malloc_list->c.c_car = alloc_simple_string(size);


with

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0xff17a000


because gcc compiled some dereferencing of this address at the above
instruction between the calls, presumably to set the cons to the
variable malloc_list.  But the address of the latter is not 0xff17a000
but

p &malloc_list
$7 = (object *) 0x102410


Anyway, I have no contacts with any mac people, so don't know where
really to turn.  First guess is a compiler bug.  Google turns up other
examples (different applications) with no obvious solutions.

Take care,
