--- Comment #2 from kargl at gcc dot gnu.org ---
There's an incredible amount of missing detail.

% cat foo.f90
program foo
   implicit none
   character(len=80) s
   call get_command(s)
   print '(A)', trim(s)
end program foo
% gfc4x -o tapt foo.f90
% ./tapt -u ./mps afiro
./tapt -u ./mps afiro
% gfc48 -o tapt foo.f90
% ./tapt -u ./mps afiro
./tapt -u ./mps afiro
% gfc47 -o tapt foo.f90
% ./tapt -u ./mps afiro
./tapt -u ./mps afiro

Works as expected on 4.9.0, 4.8.3, and 4.7.4.
