Definitely, this looks specific to the old implementation.  I'm re-evaluating
PR56113.

Just ran into this while looking for something else.  Should this be closed, as
the implementation of VRP is different now?  (i.e. no equivalence set bitmaps).

Is there a test case for this PR? I've seen this behavior in other PRs

but I can't find them.  It'd be nice to have this bug linked to such

cases (and to the "GCC is slow" meta-bug).
