[kargl at gcc dot gnu dot org]

subroutine a(fun) 
  implicit none
  integer, intent(in) :: fun
  real, external   :: funget
  real v
  v = funget(fun) 
  funget = -99.9
end subroutine a

laptop:kargl[221] gfc4x -c -O g.f90
g.f90: In function 'a':
g.f90:6: internal compiler error: in gfc_conv_variable, at
fortran/trans-expr.c:444
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Clearly, the assignment to funget is not legal.
