[Bug fortran/36176] New: TRANSFER of constant substrings

[fxcoudert at gcc dot gnu dot org]

Well, we simply don't handle simplification of TRANSFER with constant
substrings, so it gives ICEs here and there:

$ cat b.f90 
  character(len=1), parameter :: t = "x"
  write (*,*) transfer(t(1:1),0)
  end
$ gfortran b.f90 
f951: internal compiler error: in gfc_target_encode_expr, at
fortran/target-memory.c:234
