Not quite the issue. I was trying (unsuccessfully) to grep for 
"tym = x14", as suggested by Seb.  That should have been sent 
through to grep but it seems not.  The compiler should not be 
trying to execute an illegal instruction, anyway, so that seems 
to be a good target for dustmite's experiments.

While dustmite is currently chipping away, and given the correct 
link by Matheus, I am watching your 2014 DConf presentation.  
Excellent work!

Cheers,
