--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The code is indeed invalid on two counts. The first one is named commons of
different sizes (related to/duplicate of pr44882). The second is out of bound
access: the array 'e' is defined with only one element, accessing e(2) is
invalid (caught if the code is compiled with -fcheck=bounds). Thus the compiler
can do whatever it wants, e.g., considers that the loop is run only once. This
should be disabled by the option no-aggressive-loop-optimizations, but it is
not.
