    PR middle-end/64937
    * dwarf2out.c (set_block_abstract_flags, set_decl_abstract_flags):
    Replace setting argument with abstract_vec, always set BLOCK_ABSTRACT
    or DECL_ABSTRACT_P flags to 1 rather than to setting, and if it wasn't
    1 before, push it to abstract_vec.
    (dwarf2out_abstract_function): Adjust caller.  Don't call
    set_decl_abstract_flags second time, instead clear BLOCK_ABSTRACT or
    DECL_ABSTRACT_P flags for all abstract_vec elts.

    * g++.dg/asan/pr64937.C: New test.
