PR 51751 seems to concern only complex*16 failures.  Have
you had a chance to look at the real and double precision

Being semi-automatic, can you run the timing tests, too?  These
would obviously reveal possible performance regressions.  It
would also be interesting to see if -ftree-vectorize helps

Against my better judgement, I'll suggest a run with
'-O3 -ffast-math'.  It seems a large number of gfortran
users use -ffast-math.
