--- Comment #6 from Martin Jambor <jamborm at gcc dot gnu.org> ---
In my defense, even in my old code, in the call

  m_dead_ssa_debug_equiv.put (dead_ssa, *d)

I would expect the load *d to be evaluated before the inline template
function put is invoked and it feels strange that it isn't.

Anyway, I have proposed your patch on the mailing list:
