I just tried rendering a scene with an object with filter 1 and reflection 1
and max_trace_level 500 in this sparcstation. It didn't crash.
Of course it will take years to finish that render...

main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/
