           Summary: std.regex should check for valid repetition range in
                    assert mode
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2

import std.regex;

void main()
{
    auto m = "12".match(r"\d{1,0}");  // invalid range
}
-----

$ dmd -run test.d
 core.exception.RangeError std.regex(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. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I think it should throw just like any other parse error, after all patterns are
user input in certain systems (like editors).
