exited with code -1073741511

[john_god]

I've upgraded to Qt 4.6, my app was compiling ok, but now crashes in release mode. In debug mode works. It shows "exited with code -1073741511". I try qt labs for a error code list, but didnt find it so I'm asking here. Does any one knows where to get it, or what this error is about ? Using Vista btw.

is it possible you are not including a lib in release mode?

I have seen this when I forget to copy a dll into debug/release folder for testing.

Try running depends to see if it is related to a dll that can't be found, otherwise start commenting out code until you narrow it down.

[john_god]

It is a dll problem, it was looking for dll's in the system wich are from older versions, but it still crashes with dlls from current version. Very strange

[schnitzel]

have you tried deploying the app?

when you run an app debug vs. release, it will sometimes change the timing. Also check if objects get created on the stack vs. heap. I often make that mistake and things go out of scope before they get used. Timing can then make this kind of bug difficult to narrow down.

litter your code with debug prints and use debugView to see them in release mode (if you are on windows).

[john_god]

I put debug prints with qmessagebox::about(). It crashes in the main function even before entering the mainloop. I run it from explorer, it shows a message error related with invalid entry point in qtcore4.dll. This is usually if we're linking with the wrong version of the library. the problem is I disable qt path and already tried all 3 qtcore4.dll wich comes with qt, in the same file.exe directory. The problem persist, I was think it could a corrupted dll, but other project I have run fine in release. Perhaps I'll try reinstall qt, cause I running out of ideas.

[schnitzel]

try deploying your app (on a pc without Qt SDK installed) because then you can put all dll's into one folder and you know exactly which ones are being used.

[john_god]

I can do that, but dont know if it will help. Has in windows I believe that the fle.exe first search the currente directory for dll's, if it doesnt find it search in sistem dir or the path. I deleted Qt dir from path and qt dll's from system dir. The program complaigns of not having the dll's, them I copy the dlls to the current dir, and it says cannot find the entry point in some weird function. So I my opinion it's the same test has deploying it in another machine.
I just run it on linux and works fine in release and debug mode

[schnitzel]

Before you try to reinstall....
why don't you try to comment most of your code out especially whatever is in the constructor.
I would still suggest to use debug print otherwise you are depending on gui init.
Also, I have no idea on what other libraries your app depends on.

good luck

[john_god]

I just use opengl besides the basic gui dll's like qtcore.dll,... I created a empty project wich has the same problem so its not the code I think. Thanks for all the help schnitzel. I will reinstall qt but I'm work overloaded right now wich is preventing me from spending proper time to solve this issue

[Zero_G]

John_God, I'm having exactly the same issue... I just installed the new 4.6 version and I cannot run any example from the Qt Demo window, nor from the Qt Creator in Release mode!
I checked out the PATH environment variable, but it already contains "C:\Qt\2010.02.1\qt\bin", I'm looking for other references to wrong Qt DLLs...

[john_god]

I solved this issue check this thread . Let me know if this helped
