--- Comment #12 from Sam James <sjames at gcc dot gnu.org> --- You hit it already in the testsuite with UBSAN anyway, so I don't see a point in a separate test (or what it would be), unless you only saw it when running something manually w/ UBSAN rather than an existing test or with existing options.
