Hi,

Compiling open source software with 8c I see:

	"reg DI left allocated"

I haven't unpicked the code from all its #defines to see
what is actually causing this, and I assume the answer is just
to simplify the code but done anyone have an explanation as
to what might have happened?

Thanks,

-Steve

registers need to be dead after each compilation unit.
(call to yyparse()).  in this case DI was left allocated.

Yes, to get it through, but it shouldn't happen. If you can produce a
simplified test case that will be helpful.
It might involve 64-bit ints or structure assignment.
