------- Comment #1 from pault at gcc dot gnu dot org 2006-08-29 21:26 -------
Confirmed: changing the substring reference to the unambiguous
write (*,*) i, charr(i:i)
gets rid of the problem. Apparently, vene though charr is scalar, the
reference is being interpreted as an array reference.

Cooh! Not only was I full of bulls**t last night but had gone sydlexic too!
charr(i:i) is, of course, no more unambiguous than charr(i), except,
apparently, in the bowels of gfortran!
In fact, using -fdump-parse-tree, I find that charr(i) is being taken as a
character function reference. It must be easy enough to put paid to that...

(In reply to comment #2)
The standard is unambiguous: A string element must be written as charr(i:i).
character(*) :: charr
.....
print *, charr(i)
will always be interpreted as a call to an assumed character length function
charr, which is allowed if charr is a dummy function.
As to its being easy... *sigh* we'll see!

A patch is ready but I have not had time to post it.

The patch did not apply cleanly to 4.1; I will take a look tonight to try to
understand why.
