With dmd 2.048beta this program:

import std.stdio, std.regex, std.array;
void main() {
    writeln(array(match("1", regex(r"\d")).captures));
}


prints:
[1]


While this wrong program:

import std.stdio, std.regex, std.array;
void main() {
    writeln(array(match("1", regex(r"\d"))));
}


Produces:

object.Error: Stack Overflow [[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[...]

Dmitry Olshansky has suggested me to add this that comes from issue 4627:

To me this program crashes at runtime (DMD 2.053):


import std.stdio, std.regex;
void main() {
    foreach (m; match("125 155 ss25", r"\d+"))
        writeln(m);
}


If I use this line it works:
writeln(m.toString());

Now it works as expected but without .toString (which is OK IMHO there is no
toString documented).
Since 2.056+ most likely.
