          Severity: normal
          Priority: P2

This is as odd as it gets. In Windows command-line:


 type math.d


module math;
import std.stdio;
import core.stdc.stdio;
import std.conv;
import std.string;

string prompt = "Enter a number: ";
int input;

void main()
{
    write(prompt);
    auto result = to!int(readln().strip);

    writeln(result);
}

I run the test module via rdmd, and enter 45:

 rdmd math.d


D:\dev\code\d_code\bugs>Enter a number: 45
'45' is not recognized as an internal or external command,
operable program or batch file.

Now I thought I'm back to command line, but it appears I'm somehow still "in"
rdmd mode:
D:\dev\code\d_code\bugs>test
std.conv.ConvException: std.conv(727): Can't convert value `test' of type
const(char)[] to type int
std.conv.ConvException: std.conv(1129): Can't convert value `test' of type
const(char)[] to type int

Finally I'm back to command line

test


'test' is not recognized as an internal or external command,
operable program or batch file.
D:\dev\code\d_code\bugs>

Using DMD, this test module works fine:

 dmd math.d
 math.exe


Enter a number: 34
34

It looks like this was already fixed by Nick in git.

Unfortunately I can't get the latest rdmd.d from git to compile via 2.053 so I
can't test if it's fixed or not.

Andrei should push a patch for that shortly. Here's my version.

Damn, it looks like Patch from the GnuWin32 project is incompatible with Patch
distributed with git.

It does work with the one distributed with git:
D:\dev\projects\rdmd>"C:\Program Files\Git\Bin\patch.exe" -p1 < patchfile.patch
patching file `rdmd.d'

But I've tried with the GnuWin32 Patch before that and got this:
D:\dev\projects\rdmd>patch -p1 < patchfile.patch
patching file rdmd.d
Assertion failed: hunk, file ../patch-2.5.9-src/patch.c, line 339
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

2.5.9 seems to be the latest version too. Oh well..

On the flip side, I can't reproduce my bug anymore so it looks like Nick's
patch fixed it. Also thanks for the compilation patch, Vlad!
