Probably related to PR 18960, except that two
null pointers are swapped here :-)

$ cat reshape-char.f90
program main
  character(len=1), dimension(2,2) :: a,b
  a = transpose(reshape((/'a', 'b', 'c', 'd'/), shape(a)))
  print *,a
end program main
$ gfortran reshape-char.f90
reshape-char.f90: In function 'MAIN__':
reshape-char.f90:3: internal compiler error: Segmentation fault
