std.regex performance

I've finely moved to the new regex for some real code. I'm seeing
a major change in performance when checking if a large number of
words contain a digit.
The english.dic file contains 134,950 entries
With
2.056: 0.22sec
2.058: 7.65sec
I don't expect a correction for this would make it in 2.058 as it
is likely an issue in 2.057.
--------
import std.file;
import std.string;
import std.datetime;
import std.regex;
private int[string] model;
void main() {
auto name = "english.dic";
foreach(w; std.file.readText(name).toLower.splitLines)
model[w] += 1;
foreach(w; std.string.split(readText(name)))
if(!match(w, regex(r"\d")).empty)
{}
}
