This has been very enlightening information.
Is it documented anywhere which gcc features should not be trusted or
are known to have faults?

It has been always the case that additional options not enabled with
any regular -O level gets less testing and more likely has bugs. So for
mission critical functionality I would strongly suggest to stay with -O2
and not try to rely on not thoroughly tested combinations of optimization
options.
So from my point of view, the situation with -ftree-loop-linear is
fine - it's ICEing after all, not producing silently wrong-code. For
experimental options (where
I would include all options not enabled by -O[123s]) known wrong-code bugs
should be fixed.
That's my 2c,
Richard.
