I suspect that PR breakpoints/23300 is a regression, and maybe PR mi/23312
as well.  I plan to look at 23300 (though I don't mind if someone gets
there first).

Also I found out that this code in symfile.c:

      for (auto iter : new_objfiles)
	gdb::observers::new_objfile.notify (objfile);

... had a bug introduced by

    commit 4c404b8be6b1d8759eed50366207fc0e2e47d2b1

        Use std::vector in reread_symbols

Previously it read:

-      for (ix = 0; VEC_iterate (objfilep, new_objfiles, ix, objfile); ix++)
-	observer_notify_new_objfile (objfile);

... where "objfile" was used in the iteration -- so now the wrong
objfile is being passed to the observers.

Fixing this is trivial, but I suppose a test case would be good.  Maybe
the simplest way would be a Python test (so it can hook into the
observer) plus a shared library?  I am actually not sure.  I guess I'm
sort of hoping not to write it.
