Hi Paul,

duuuh! Please find them attached.
the patch LGTM. Thanks!
However, I have comments on the new testcase associate_60.f90:
subroutine pr93813 is missing an allocation of x, e.g.:
allocate (t :: x)
otherwise it would be invalid. Please check and fix.
Interestingly, subroutine pr92779 exhibits a small memory leak
with memory allocated by the spread intrinsic. I played a little
and found that the leak depends on the presence of trim(): omitting
trim() removes the leak. But looking at the related pr, it seems
that trim() was essential, so omitting it is likely not an option.
I think the best way is to proceed and to open a PR on the memory
leak rather than leaving pr92779 open. What do you think?
Cheers,
Harald
Thanks
Paul

Hi Paul,
I don't see the new testcases. Is this an issue on my side,
or did you forget to attach them?
Thanks,

Dear All,
Please find attached a slightly updated version of the patch with a
consolidated testcase. The three additional testcases are nothing to do
with associate and test fixes of character related bugs.
OK for mainline?
Cheers

* resolve.cc (resolve_assoc_var): Handle parentheses around the
target expression.
(resolve_block_construct): Remove unnecessary static decls.
* trans-array.cc (gfc_conv_expr_descriptor): Guard string len
expression in condition. Improve handling of string length and
span, especially for substrings of the descriptor.
(duplicate_allocatable): Make element type more explicit with
'eltype'.
* trans_decl.cc (gfc_get_symbol_decl): Emit a fatal error with
appropriate message instead of ICE if symbol type is unknown.

'previous' and use if end expression in substring reference is
null.
(gfc_conv_string_length): Use gfc_conv_expr_descriptor if
'expr_flat' is an array.
(gfc_trans_alloc_subarray_assign): If this is a deferred string
length component, store the string length in the hidden comp.
Update the typespec length accordingly. Generate a new type
spec for the call to gfc_duplicate-allocatable in this case.
