Comment (by thomie):

 Merged to 7.10 in commit ccb7d96da42663407f1cd73355821ca5a7f55e7f:
 {{{

     Return a [HsImplBang] from dataConImplBangs even with NoDataConRep

     This fixes Trac #9969, a new crash in T7562 that I somehow missed when
     fiddling with HsBang

     (cherry picked from commit 327ce1d336c8fbdb068be900a187f96d1c60b851)
