--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
This looks very much like an error I looked at before.
I think that was for 'select rank (y => x)', which
has the same issue as 'select type (y => x)' or
as this PR shows 'associate (y=>x)'.
Additionally, the following points to the 'x' (gfc_current_location)
and not to 'y'; we should save that location for the error message:
11 | associate (y => x)
| 1
Error: Assumed shape array at (1) must be a dummy argument
That's something we should fix in match.c, where we have:
if (gfc_match (" %n =>", newAssoc->name) != MATCH_YES)
...
if (gfc_match (" %e", &newAssoc->target)
...
newAssoc->where = gfc_current_locus;
for associate but likewise for select type/rank.
* * *
In resolve.c, there is:
if (((as->type == AS_ASSUMED_SIZE && !as->cp_was_assumed)
|| as->type == AS_ASSUMED_SHAPE)
&& !sym->attr.dummy && !sym->attr.select_type_temporary)
the latter is set for both select type + select rank. Looks as if we also need
a check like:
sym->assoc
or something like that.
We probably should audit all code which uses select_type_temporary or
sym->assoc to see whether we need to add a condition for associate or select
type/rank there as well.
