Crash report analysis - help needed

[ufo]

Hi all.
So I made a prog that hooks PrintText and from time to time (quite random and rarely) there happen to be a debug crash.

I've finally made it to store that debug info, but now I need help understanding it, as I don't know if it's my prog that's causing the debug, or is it server fault.

Additional info:
Server is an OT for Tibia 8.0

Screenie of the report:

Do you null the last char?

[ufo]

The text is passed to the function as a string so I assumed it IS null terminated (btw it's coded in Delphi7).
But that would be weird as it should either work or not at all.
And it works fine and very rarely debugs.

Thanks for the idea though - will look into that.


What's that last packet thing though ?
Is it encrypted or decrypted ?
'cuz I can't understand it at all...

The reason for the crash seems to be at the very last line of the debug notes.

Length=14, strlen(Text)=13..

Try it:

Text[Length(Text)-1] := #0;

@Dark Pallys
That's what I don't get at all...
What's that 14 for ? Length of a packet it should be or what?
Might be that it's the missing zero char at the end of a string and that's why the length is greater than actual string length...

@megano0body
I did something similar to this
[code=delphi]procedure AddUserText(nText:string;nX,nY,nRed,nGreen,nBlue,n :integer; nAlign: integer=alLeft);
begin
with UserTextList[n] do begin
enabled:= true;
text:= nText + #0; // <<< added the " + #0" here, so it always ends with zero char
x:= nX;
y:= nY;
Red:= nRed;
Green:= nGreen;
Blue:= nBlue;
Align:=nAlign;
end;
end;[/code]

But since this is a very rare debug, I'll have to wait for the answer a bit...
It's been over a week since I debugged before this one, and I play the OT daily :S

But yea... thanks for your help ^.^
