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. r~
