I'm unsure how to deal with this. It is an ICE, and it happened
throughout the RTL stage as before. But the signature seems to be a
different one.
It could be "bad" with the actual issue we look for hidden behind this.
It could be "good" as well with the actual issue we look fixed but hidden
behind this.
Or it could be "bad" as in, this is the same issue but with a different
signature.
For the time being I'll handle it as bad, with some luck we get our old
trace back further down the bisect. But @Doko please have a look at the
trace above (maybe it is a known one) and advise.
