I've tried both the CodeSourcery version and 2.2.0:

Sure - how best should I do this, as an attached tgz?

If by that you mean "copy the toolchain" - yes, the toolchains are
identical (at least the CodeSourcery chains are - the newer chain is part
of an ongoing, but currently stalled, project to bring the tools more up
to date).

That may be (I assume you mean "uninitialized memory bug in the
assembler"), but it's odd that it is so consistently wrong on my machine
and so consistently right on my coworkers.
