--- Comment #28 from Alexander Monakov <amonakov at gcc dot gnu.org> --- The bug is about the issue of lacking diagnostics, it should be fine to make note of various approaches to remedy the problem in one bug report. (in any case, all discussion of the Valgrind-based approach happened on the gcc-patches mailing list, not here)
