--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Now the question is whether/why we don't see any DW_TAG_inlined_subroutine
and why we inline anything at -O0 at all.  That said, the middle-end does not
perform any inlining but the C++ FE inserts

      finally
        {
          [/usr/include/c++/10/bits/basic_string.h:525:59]
std::allocator<char>::~allocator
([/usr/include/c++/10/bits/basic_string.h:525:59] &D.37009);
        }
    }
  finally
    {
      [/usr/include/c++/10/bits/basic_string.h:525:59] D.37009 = {CLOBBER};
    }

so somehow we leak the location of the dtor declaration to the GIMPLE stmt
created by the gimplifier.

Bisection is probably what is easiest to get us forward.
