czardas Posted May 31, 2010 Posted May 31, 2010 (edited) A bug in one of my scripts had somehow gone unchecked by me: simply because it was not causing any problems. I seem to remember having doubts about it at the time, and perhaps I had dismissed the possibilty of a divisor becoming zero during a particular operation which involved the Mod function. Amazingly, the script always seemed to work in any case. So apart from now making myself feel like a clown, I was surprised to receive a Microsoft bug report when I tried to run the script with the latest AutoIt interpreter. It didn't take me long to track the problem, and after running tests I discovered the following.AutoIt Version: 3.3.0.0Mod(1,0) => Returns -1.#INDAutoIt Version: 3.3.6.1Mod(1,0) => Send Error Report to MicrosoftI couldn't find any reference to changes in error handling. It could be relevant to the Devs. Both tests were run on XP pro service pack 3. This is the first time I have encountered a Microsoft Bug Report while using AutoIt, otherwise I would not have mentioned it. Edited May 31, 2010 by czardas operator64 ArrayWorkshop

czardas Posted May 31, 2010 Author Posted May 31, 2010 Thanks for the responce. I really have no idea if it's a bug, related to any other issues, or not. I am used to getting errors from the handler, but not from the OS. It's really a consequence of an error in my code. But it seemed a bit out of the ordinary to get that message. I don't know if it helps at all. operator64 ArrayWorkshop
Richard Robertson Posted May 31, 2010 Posted May 31, 2010 It is a bug that it would hard crash like that.

Mat Posted June 1, 2010 Posted June 1, 2010 It's fixed in the next version according to the ticket. AutoIt Project Listing
czardas Posted June 2, 2010 Author Posted June 2, 2010 It's fixed in the next version according to the ticket.Presuming it is the same issue. operator64 ArrayWorkshop
jvanegmond Posted June 2, 2010 Posted June 2, 2010 Presuming it is the same issue. It's not. The ticket says: Fixed by revision [5432] in version: 3.3.1.7 Looks like that change has probably created this bug since it's not in 3.3.0.0 and in my 3.3.4.0 it does crash. github.com/jvanegmond
czardas Posted June 2, 2010 Author Posted June 2, 2010 I decided I ought to create a new ticket. operator64 ArrayWorkshop
Valik Posted June 2, 2010 Posted June 2, 2010 You are correct, the code was fixed so that integers are treated as integers and not converted to floats. This introduces a divide-by-zero possibility.
