--- Comment #5 from Andrey Guskov <andrey.y.guskov at intel dot com> ---
This is the actual guilty line:

sw_absorption.F90:    chlamnt = 10**(logchl)

It computes 'chlamnt' and then compares it to the list of acceptable values.
When -Ofast is enabled, CPU2017::628 considers 'chlamnt' unacceptable.
