Thanks.

The segfault is occurring while attempting to display
the relations in 2 interlocked dependency loops while ordering.

Can you try reproducing with this patch?

The patch saves the current dependency index "just in case" and
adds a range check assertion on the dependency set index (which seems
to be the likeliest failure from looking at the backtrace).
