    d: Fix ICE using non-local variable: internal compiler error: Segmentation
fault

    Moves no frame access error to own function, adding use of it for both
    when get_framedecl() cannot find a path to the outer function frame, and
    guarding get_decl_tree() from recursively calling itself.

    gcc/d/ChangeLog:

            PR d/96254
            * d-codegen.cc (error_no_frame_access): New.
            (get_frame_for_symbol): Use fdparent name in error message.
            (get_framedecl): Replace call to assert with error.
            * d-tree.h (error_no_frame_access): Declare.
            * decl.cc (get_decl_tree): Detect recursion and error.

    gcc/testsuite/ChangeLog:
