/*
 * 989_strglobeq_run — #154 regression pin. Compile + run the strglobeq
 * fixture under the C-side `ww run` driver (cstage w6c) and assert exit 0.
 *
 * The bug (str== fast-path read the global str header off BP+0 instead of
 * name(SB)) is a CSTAGE silent miscompile; byte-id 990-997 can't see a
 * runtime-value miscompile, so only this value check catches it. Same
 * thin-wrapper shape as 989_letshadow_run.
