--- Comment #16 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- Created attachment 37190 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37190&action=edit Test case that still fails Hi Paul, > (i) To fix the ICE in trans.c. This is fixed by the change to trans-stmt.c. > Note that I have not checked to see if this has been cured - my tree is > somewhat out of date. In anycase, expr3 should never be coming back as a > NOP_EXPR; and Andre already fixed this one (PR 69011). > (ii) Fix the original problem in sorting.

I tried out this part of your patch (with Andre's fix) and got yet another failure on a modification of the original test case. Now sorting the right-hand part of the array fails: Sorting ...
