This is short-sighted, for the reason I pointed out in my earlier
post. How would you go about reporting an ICE for a 100k LOC test
case without any idea about where to start looking?
In fact, that's precisely what happened to the guys at Weka
before, although I'm certain they are not alone with this. They
encountered ICEs when updating the compiler version with no way
to narrow it down. Of course, *I* could just build DMD with
symbols and have a look at what was going on in GDB, but that's
the luxury of being a compiler dev.
Let's not pretend the user can debug the compiler.
They can create bug reports to help other people to do so, though.
