Testcase:
subroutine f1 (a)
character(len=1) :: a(7:)
character(len=12) :: b
character(len=1) :: c(2:10)
write (b, a) 'Hell', 'o wo', 'rld!'
if (b .ne. 'Hello world!') call abort
write (b, a(:)) 'Hell',

Actually, module isn't needed for the ICE:
subroutine test (v1, v2, v3, v4)
integer, target, allocatable :: v1(:)
character(len=8), target, allocatable :: v2(:)
integer :: v3, v4, v5
write (*,v2(1:v3))

This may be a stupid question, but are the codes in comments #0 and #1 valid?
The allocatable variables are used without being allocated, isn't it?

Whether this is valid or not I have no idea.
Just bear in mind that this is a distilled compile time testcase, not intended
as runtime testcase, for runtime testcase obviously something would need to
allocate the

allocatable and target attributes aren't needed btw, the following ICEs as

ICEs too (on the second or third write stmt).

Shorter, but gives not an error message but simply segfaults. (By the way, for
all tests I tried, gfortran 4.1 to 4.4 crashes, i.e. it is no regression.)
Seemingly, no one had tried before to pass an array to the

Well, gfc_convert_array_to_string seems to handle AR_FULL arrays correctly, but
probably just the other arrays does not.

A different testcase that segfaults even a little bit earlier:
subroutine test()
interface
function f()
character(len=1) :: f(5)
end function f
end interface
write (*, f()) 1
end subroutine test

Paul, this PR might interest you - esp. as you have most experience in that
part of the compiler. (If you are/feel swamped, feel free to de-CC yourself.)
