           Summary: [7/8 Regression] -fsanitize=undefined ICE
           Product: gcc
           Version: 7.1.1
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

#ifdef __SIZEOF_INT128__
typedef __int128 T;
typedef long long int T;
struct A
  A (long);
  T a;
A::A(long c) { long b = a % c; }

ICEs with -fsanitize=undefined on x86_64-linux with both -m32 and -m64 starting
with r245945.  Reduced from i686-linux bootstrap-ubsan ICE on stor-layout.c.
