I hate to say it, but you forgot to add the testcase again... :-(
The patch fixes your "extended" testcase in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107900#c2
but the original one in comment ICEs for me here:
% gfc-14 pr107900.f90
f951: internal compiler error: Segmentation fault

It hits an assert here:
9790 st = gfc_find_symtree (ns->sym_root, name);
9791 gcc_assert (st->n.sym->assoc);
My tree is slightly modified, but the changes should not have
any effect here.
Can you please have a look, too?
Thanks,
Harald
