Testcase:
subroutine option_stopwatch_s(default_clock)
character, intent(in) :: default_clock
call option_stopwatch_a((/default_clock/))
end subroutine option_stopwatch_s

pc64:~> ~/checkin/bin/gfortran t.f90 -fdump-tree-all
t.f90: In function ‘option_stopwatch_s’:
t.f90:3: internal compiler error: in gimplify_expr, at gimplify.c:4658
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
