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.
