--- Comment #1 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Tue Dec 10 20:06:58 2019 New Revision: 279183 URL: https://gcc.gnu.org/viewcvs?rev=279183&root=gcc&view=rev Log: PR c++/92560 - ICE with decltype and rewritten operator. A call as the immediate operand of decltype is handled differently; we don't create an object of the return type as we do normally. But in the case of a rewritten operator, we're adding another call as a wrapper, so the inner call doesn't get the special handling. * call.c (build_new_op_1): Clear tf_decltype on inner call. Added: trunk/gcc/testsuite/g++.dg/cpp2a/spaceship-decltype1.C Modified: trunk/gcc/cp/ChangeLog trunk/gcc/cp/call.c
