Reduced test-case:

$ cat pr107244.c
typedef char xchar;
struct monst {
  struct monst *nmon;
  short movement;
  char malign;
  xchar mx, my;
  unsigned : 7;
  unsigned : 7;
  unsigned : 11;
  unsigned mleashed : 1;
} *level_0, *unleash_all_mtmp;

void
unleash_all() {
  for (; unleash_all_mtmp; unleash_all_mtmp =3D level_0)
    unleash_all_mtmp->mleashed =3D 0;
}=
