I have a rather simple view of this sort of thing.  If I feed input to a 
program and the program crashes, that's always a bug.  This is true even if the 
input was "invalid" in some way.

That said, 700k lines in a single source file is a bit extravagant, but I see 
no way that such a thing could be legitimately called "invalid".  If it's all 
one function (or worse yet, one basic block), I would not be at all surprised 
if it exceeds a resource limit on how big a function can be, but if so, the 
expected output would be an error message, not a crash.
