So, if we assume the user cannot debug if he hit an compiler bug, 
I as a compiler developer would at least like to receive a report 
containing a simple number, to identify which of the 830 
assert(0)'s in the code that I deemed to be unreachable was 
actually hit.

Because even if I don't receive a reduced testcase, I have a 
strong hint what assumption I should re-think, now that I know 
that it is effectively NOT unreachable.

Could we agree so far?

SO what problem would it be to give the assert(0)'s a number each 
and print out a message:
"Compiler bug: assert #xxx was hit, please send a bug report"
?
