            Bug ID: 83556
           Summary: ICE in gimplify_expr, at gimplify.c:12004
           Product: gcc
           Version: 7.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: p.pettinato+gcc at gmail dot com
  Target Milestone: ---

Compiling the following on gcc 7.2.0 (Ubuntu Artful, x86_64-linux-gnu) fails:

int func()
{
    return 1;
}

struct Data
{
    int good = func();
    int bad = 1;
    int ugly = good ? 1 * bad : 2 * bad;
};

struct MoreData
{
    Data d{};
};

int main()
{
    MoreData m{};
    return m.d.ugly;
}


Output:

$ g++ test.cpp -o a
test.cpp: In function 'int main()':
test.cpp:10:37: internal compiler error: in gimplify_expr, at gimplify.c:12004
     int ugly = good ? 1 * bad : 2 * bad;
