could be posted for review soon.
The patch is OK to commit along with a testcase from this PR.

It would be nice if a fortraner could make the testcase not output to
stdout/err
but to /dev/null instead.
open(6,'/dev/null')
didn't work for me ;)
Just to make a testcase suitable for the testsuite.

stupid me. open(6,file='/dev/null') works.

Here is a testcase which also checks the resulting array is correct:

CONTAINS
PURE FUNCTION s2a_3(s1,s2,s3) RESULT(a)
CHARACTER(LEN=*), INTENT(IN) :: s1, s2, s3
CHARACTER(LEN=1000),

A slight modification of the example in comment #2:
MODULE TEST
CONTAINS
FUNCTION s2a_3(s1) RESULT(a)
CHARACTER(LEN=*), INTENT(IN) :: s1
CHARACTER(LEN=LEN(s1)) :: a(3)
a(1)=s1
END FUNCTION

I was wrong in marking this as a middle-end issue.
We have:
char[0:D.1026][1:4] * __result.0;
char * temp.87;
...
temp.87 = (*__result.0)[0];
__builtin_memset (temp.87 + (unnamed-unsigned:32) _s1, 32, 4 -

note this might get cleared up with pointer_plus.
I have not tried it there yet but i will be posting a patch and committing
soon.

The segfault is still happening with today's code. This is the simplest case I
find to trigger it.

I assume this is another incarnation of this bugs but leads to a segfault and a
slightly different valgrind output:
MODULE TEST
CONTAINS
PURE FUNCTION s2a_3(s1,s2,s3) RESULT(a)
CHARACTER(LEN=*), INTENT(IN)
