--- Comment #1 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
1. write also fails (no surprise there)
2. ca is OK, ca(1:3) is not.
$ cat u.f90
program main
implicit none
integer:: i
integer, parameter:: N = 10
character(len=:), dimension(:),allocatable:: ca
character(len=50):: buffer
allocate(character(len=N):: ca(3))
buffer = "foo bar xyzzy"
ca(1) = "foo"
ca(2) = "bar"
ca(3) = "xyzzy"
write (*, '(3A5)') ca
write (*, '(3A5)') ca(1:3)
end program
$ gfortran u.f90 && ./a.out
foo bar xyzzy
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
