Bug 11775 – std.regex should check for valid repetition range in assert mode

----- import std.regex; void main() { auto m = "12".match(r"\d{1,0}"); // invalid range } ----- $ dmd -run test.d > [email protected](5019): Range violation Note that the exception is internal while trying to access an invalid index in an array. With -noboundscheck there will be no exceptions thrown. I think at least in assert mode ( version(assert) ) the repetition range should be verified to be valid.

https://github.com/D-Programming-Language/phobos/pull/1791 I think it should throw just like any other parse error, after all patterns are user input in certain systems (like editors).
