The problem here tends to be that there is *no* `reporting' at all: all
GCC sees is that some of its pointer-chases go off into nowhere because
of (from GCC's viewpoint) random bit-flips in its pointers.
And GCC does a *lot* of pointer chasing; *far* more than any other
program you're likely to run except perhaps for the kernel itself.
