Out of range pointer error

[Marco Gerards]

Hi,

There is possibly a bug in the mm.c code (I think...).  For the PPC
port I initialize one region (address: 0x300000, size: 0x100000).  I
get the `out of range pointer 0x300000' error after a while.

The problem is, AFAIK, caused by pupa_malloc, it allocated memory on
the location 0x300000, but the header is located on that place as
well ((*r)->addr in get_header_from_pointer is set to 0x300010).

So I think the header needs to be marked as allocated, right?  Anyway,
I will have a look at it, unless someone else can fix this in a few
minutes.

Thanks,
Marco
