Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Known to work| |6.0 Resolution|--- |FIXED Known to fail| |4.7.4, 5.3.0 --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- This is fixed in GCC 6 but still broken in GCC 5. GCC 4.5 complained: t.c:2: error: redefinition of typedef ‘yyx_handle’ t.c:1: error: previous declaration of ‘yyx_handle’ was here since GCC 4.6 we accept the code and do not emit the typedef in debug info. Thus not a regression, fixed.
