--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Assuming that the gurus' all agree that answer should be
sum_parent
sum_child
sum_child
I confirm this PR as a regression. The related history is pretty chaotic:
[macbook] f90/bug% /opt/gcc/gcc4.8p-187200/bin/gfortran pr63733.f90
[macbook] f90/bug% a.out
sum_parent
sum_parent
sum_child
[macbook] f90/bug% /opt/gcc/gcc4.8p-187291/bin/gfortran pr63733.f90
[macbook] f90/bug% a.out
sum_parent
sum_child
sum_child
likely r187226 (pr53255), back ported to 4.7 as r187232.
