Something's broken. But it's tricky.
For instance, running with -R 2G works, but -R 3G does not.
Now, I'll also note for the record that 2G is the most that
a mips32 userland application ought to be able to reference
anyway -- anything with the high-bit set is by definition
kernel space.
So while I have yet to track down exactly what went wrong,
I have a suspicion that it might actually be related to the
incorrect placement of the objects in the address space.
