--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, can you bisect this a bit?  It may be a latent issue is uncovered.
Disabling compare-debug might also help getting better backtraces.

Looks like loop-invariant has inconsistent DF state somehow.  In the

        ../../src/gcc/df-core.c:1594

frame it is interesting to know the problem causing this.

Maybe the backtrace is also completely bogus since there shoud be no
hash-tables involved here...

P1 until we know some more.
