This release only avoids this issue in the uses of ``unsafeCoerce`` + in ``Data.Typeable.Internal``, which was the proximate cause of + :ghc-ticket:`16893`. + + However, it is possible that this bug could manifest in user-code using + ``unsafeCoerce`` to perform dynamic type checks. See the :ghc-ticket:`ticket + <16893>` for details. + +- The simplifier can optimise away some applications of the ``touch#`` primop + when it can prove that the ``touch#`` is unreachable due to divergence or + synchronous exception, resulting in memory unsoundness. Users requiring + ``touch#`` behavior are advised to only use ``touch#`` to implement + continuation-passing-style primitives (e.g. in the style of + ``withForeignPtr``) bearing ``NOINLINE`` pragmas (to avoid inappropriate + simplification). See :ghc-ticket:`17760` for details. + +Included libraries +------------------ + +The package database provided with this distribution also contains a number of +packages other than GHC itself.
