            Bug ID: 104583
           Summary: [12 regression] ICE dolphin-emu at
                    cp/cp-gimplify.cc:746
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

Noticed ICE today when was building dolpjin-emu with a weekly gcc snapshot and
current gcc master.

Minimal reproducer:

    // $ cat bug.cc
    struct TVec3 {
      TVec3();
      int data;
    };
    using Vec3 = TVec3;
    struct {
      Vec3 position{};
    } EmulatePoint_state;
    void EmulatePoint() { EmulatePoint_state = {}; }

/tmp/gcc/xg++ -B/tmp/gcc -c bug.cc -freport-bug
bug.cc: In function ‘void EmulatePoint()’:
bug.cc:9:42: internal compiler error: in cp_gimplify_expr, at
cp/cp-gimplify.cc:746
    9 | void EmulatePoint() { EmulatePoint_state = {}; }
