--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> --- The particular assertion was added in r14-5930-gf31a019d1161ec aka f31a019d1161ec78846473da743aedf49cca8c27, so the test failures presumably affect gcc 14 and trunk. There may be other dormant issues on older releases due to not resetting any of the state in varasm.cc.
