Hi All,
This problem caused the gimplifier failure because the reference chain
ending in an inquiry_len still retained a full array reference. This had
already been corrected for deferred character lengths but the fix extends
this to all characters without a length expression and integer expressions,
which is the correct type of course, that retain a full array_spec. The
nullification of the se->string length in conv_inquiry is a
belts-and-braces measure to stop it from winding up as a hidden argument in
procedure calls.
OK for trunk and, after a decent delay, backporting?
ENOTESTCASE.
Nevertheless the patch LGTM and is also OK for backporting.
Thanks for fixing this!

Fortran: Fix assumed length chars and len inquiry [PR103716]

* resolve.cc (gfc_resolve_ref): Conversion of array_ref into an
element should be done for all characters without a len expr,
not just deferred lens, and for integer expressions.
* trans-expr.cc (conv_inquiry): For len and kind inquiry refs,
set the se string_length to NULL_TREE.
