--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r255790.

Another testcase that also ICEs since that revision:
typedef __SIZE_TYPE__ size_t;
extern void *memcpy (void *, const void *, size_t);
extern char *strlen (const char *);
extern char c[2];

void
foo (char **q)
{
  memcpy (c, "a", 2);
  q[0] = strlen (c);
}
