           Summary: A stack overflow with writeln
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



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.
