There is no one patch for verify_local_live_at_start failures.
That's an extremely generic "something went wrong" sort of check.
Every single instance of this must be investigated separately.

In particular, the patch above *only* fixes one rare instance
in which non-pic codes uses a global register variable that is
the same as the pic register.

So it's certain that it's not going to help you.
