--- Comment #46 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- Note: a) the patch will should be OK for 4.8 but not for 4.7. b) the read-side does not ICE but will likely generate invalid code. => a patch for the read-side is sill pending for review: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02291.html
