Reproduced. This is a problem with GCC and the offset that ldrsb is able
to access. I have filed this issue with our internal systems tracker.

This is a very specific bug, and any changes to the code will make the
output insn sequence the right length and the load will assemble. The
only workaround I can recommend is reordering some of the variable read
and writes.

Cheers,
Carlos.
