void main() { auto x = 9223372036854775808; // long.max + 1 } compilation fails, but specs on https://dlang.org/spec/lex.html#integerliteral tell, that it will not. See https://forum.dlang.org/post/[email protected]

Because it's been implemented this way for 19 years now, and the compiler behavior matches C, I recommend that the spec change rather than the compiler.

I changed this to a spec bug, rather than a compiler bug.

(In reply to Walter Bright from comment #3) > I changed this to a spec bug, rather than a compiler bug. Nitpicking, but: It was a spec bug from the very beginning and I was surprised to see an implementation fix PR...
