This one is strange; it is with recent trunk.

ig25@linux-fd1f:~/Krempel/Char-4> cat foo.f90
program main
  implicit none
  character(len=3) :: c(3)

  c = 'x'

  print '(3(A,"|"))', (/ (/ trim(c(1)), 'a' /)//'c', 'cd' /)
  print '(3(A,"|"))', (/ (/ c(1)(1:len_trim(c(1))), 'a' /)//'c', 'cd' /)
  print '(3(A,"|"))', (/ (/ c(1)(1:1), 'a' /)//'c', 'cd' /)
end program main
ig25@linux-fd1f:~/Krempel/Char-4> gfortran foo.f90
ig25@linux-fd1f:~/Krempel/Char-4> ./a.out
xc|ac|cd|
x |a |cd|
xc|ac|cd|

The second line should be identical to the first and third one.

Modified from nested_array_constructor_2.f90, BTW.

Goes back at least to 4.4.1, so probably not a regression.
