An interesting exit code...

[Kealper]

Well, I'm working on a telnet remote console module for an IRC bot that I'm making, and it's worked just fine for quite a while, until I started doing some overhauling of some old, messy code(It continued to work after the main overhaul, so that doesn't appear to be the problem). As of yesterday, I broke it somehow, and after starting it up through SciTE to see what line is causing the crash, it shows this:

!>20:16:09 AutoIT3.exe ended.rc:-1073741819
+>20:16:11 AutoIt3Wrapper Finished
>Exit code: -1073741819    Time: 22.316

Now, I've never seen anything like that, and it has an exit code of -1073741819...Anyone ever seen this before?

It might be something stupid that I did late last night to break the script without realizing it, but as of right now, I'm stumped

EDIT: Oh, yea and I think AutoIt is actually crashing, as the icon stays in the system tray. A normal "crash" throws an error in a message box, tells you what went wrong, and closes properly after pressing Ok, this just dies instantly with that strange error/exit code.

You clearly didn't try to search the forum for this code.

Yea, sorry, didn't occur to me

You can delete the topic if you want

Ok, I searched for about an hour and a half, but could not find any definitive answer on what this error is. So I did some real in-depth debugging and finally nailed the problem in my script, and was able to recreate the hard crash with the simple script below. (maybe it can help others find the problem in their programs quicker, should they make the same mistake.)

This hard crashes AutoIt 100% of the time on a WinXP SP2 x86 machine and a Win7 x64 machine.

It appears to happen when you have a ContinueCase on the last case of both a Switch or a Select

For $i = 1 To 3
    Switch $i
        Case 1
            ConsoleWrite("$i = " & $i & @CRLF)
        Case 2
            ConsoleWrite("$i = " & $i & @CRLF)
        Case Else
            If $i = 3 Then ContinueCase
    EndSwitch
Next

Shouldn't that be caught at compile time then?

[Kealper]

I would have thought that too, but it will compile fine, show no problems until it gets to that specific thing, then crashes.

EDIT: just checked, passes Tidy and everything

I've never reported a bug before, but ok, there's a first time for everything

*sigh* I really should be more active on here...lol

Just got that error myself

!>17:18:14 AutoIT3.exe ended.rc:-1073741819

I have select..case..endselect, but no continuecase

Just a shell.explorer2 object in a gui, and it was just idle when it crashed.

Than its most likely a differant problem.

The exit value -1073741819 is not a crash PID, that would be ... to easy.

This number means a 0xC0000005 access violation occured.

Just got this error again while trying to play xvid in gui.

It happens every time, must be my scabby old RAM.
