--- Comment #20 from Julien Margetts <jmargetts at ocz dot com> ---
It is the gcc_assert (REG_P (operands[0])); in arm_reload_in_hi which fires,
which as far as I can see is still in trunk today.

At this point rtx operands[0] looks like this:

08 2d c2 7a 53 2b 00 00

The first pass through this code (no assert) looks like this:

80 b8 c1 7a 53 2b 00 00 

NOTE: This was recreated by merging both patches from trunk into otherwise
unchanged 4.9.3 release sources, as I am trying to back port this fix to 4.9.3
