--- Comment #4 from Mikael Pettersson <mikpe at it dot uu.se> ---
I can reproduce the SEGV now, it was masked by my standard build's
--with-tune=cortex-a9 option.

The SEGV doesn't reproduce any more after r188742 + r188743, which changed the
way the ARM backend expands epilogues.  I don't immediately see the connection
between that change and the garbage reg_last->sets value.
