--- Comment #2 from Alexey Izbyshev <izbyshev at ispras dot ru> --- > Is there a way to bind GCC to a specific core and test again? Yes, `repro.py` can be run via `start /affinity MASK`. I've started two experiments, with one- and two-processor masks. They haven't crashed after several minutes, but I'll wait longer and then report the result. Anyway, it seems that crashing in `gcc_unreachable()` due to NULL `context->printer` is still kind-of-a-bug, since it makes it difficult to understand what went wrong in the first place.
