Created an attachment (id=785)
Full D program that reproduces bug.

In this code:

try
{
 foreach( r; result.captures)
      writeln(r);
}
catch(Exception * exc)
{
  //we never get here
}

if result is empty the application exits. And no exception is caught.

Full program attached.

Tested with D2 compiler. Version: not specified. Size: 1.340.444 bytes

Mass migration of bugs marked as x86-64 to just x86.  The platform run on isn't
what's relevant, it's if the app is a 32 or 64 bit app.

2010 ... that was a year before the new std.regex.
Now it just works and empty result is, well, just an empty range. This is what
I see:

Running Test1()
Running Test2()

Press any key to continue...

The last line is printed by the app so no crashes here (Win32).
