I attach the config.log ... then I noticed...
abinit-5.2.3/config.log:FCFLAGS_OPT='-O3 -tpp1'
abinit-5.2.4/config.log:FCFLAGS_OPT='-O2'
abinit-5.3.0/config.log:FCFLAGS_OPT='-O2'
abinit-5.3.2/config.log:FCFLAGS_OPT='-O2'
abinit-5.3.3/config.log:FCFLAGS_OPT='-O2'
abinit-5.3.4/config.log:FCFLAGS_OPT='-O2'

Oh, yikes !

Yes, that was when we decided with Xavier to put safer default optimisations. I had forgotten about that, sorry.

Bon week-end !

Yann.
