Even if you fix this particular bug, you are still running into the unfortunate
situation on the 32-bit MIPS architectures that there is not enough virtual
address space per process for Rust to work so you will always end up in
out-of-memory situations when building rustc natively on 32-bit MIPS.

I have done extensive testing and tried lots of different approaches to
reduce the memory footprint of the Rust compiler, but so far I have
never succeeded in building rustc natively on 32-bit MIPS.
