           Summary: [10/11/12 Regression] ICE in gimple_split_edge, at
                    tree-cfg.cc:2960

Changed between 20190609 and 20190616, at -O3 or -Ofast :


$ cat z1.c
#include <setjmp.h>
struct longjmp_buf {
  jmp_buf buf;
};
void g ();
void f ()
{
  int i, n;
  long *a;
  long *args;
  struct longjmp_buf b;
  setjmp (b.buf);
  for (;;)
    {
      for (i = 0; i < n; i++)
        a[i] = args[i];
      g ();
    }
}
