--- Comment #17 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Fri Jan 10 18:46:57 2020 New Revision: 280126 URL: https://gcc.gnu.org/viewcvs?rev=280126&root=gcc&view=rev Log: PR c++/93173 - incorrect tree sharing. My patch for 93033 wasn't sufficient to handle all the possible sharing introduced by split_nonconstant_init, and it occurred to me that it would make sense to use the same unsharing technique as unshare_body, namely copy_if_shared. PR c++/93033 gcc/ * gimplify.c (copy_if_shared): No longer static. * gimplify.h: Declare it. gcc/cp/ * cp-gimplify.c (cp_gimplify_init_expr, cp_gimplify_expr): Use copy_if_shared after cp_genericize_tree. * typeck2.c (split_nonconstant_init): Don't unshare here.
