Subject: Re: [4.6 Regression] Unnecessary temporaries
increase the runtime for channel.f90 by ~70%
4.3 is not so easy - it's throwing a load of regressions. I'll spend
some time tonight to try to understand why. If I don't see it, I will
close this PR as FIXED; after all this bug goes gack to gfortran-3.5,
so it has taken 10years for it to come up :-)
