--- Comment #2 from Iain Sandoe <iains at gcc dot gnu.org> ---
So the fix for PR105287 was too ambitious - and reveals that we are missing to
name some variables that should be promoted.
Rather than delay for a second fix, the proposal would be a partial reversion
of r12-8308-g15a176a833f23e, like so (which would be more suitable for the
branch). This does fix the new issue (and still fixes the analyser one) in my
local testing.
