QtCreator crashed and now will not start due to segfault
-
I get a segmentation fault when I run it from the cmdline both without and with arguments.

There's, oohh, a 1% chance that if you try running Qt Creator from within a debugger like Visual Studio (if you have that...), when it faults you'll get enough information from the stack trace to hazard a guess as to where it's going wrong... -
I just debugged it and got this: Exception thrown at 0x670E5DA7 (Qt5Core.dll) in qtcreator.exe: 0xC0000005: Access violation reading location 0x7E5B8721.

Is it possible that the wrong Qt DLLs are loaded? Have you changed the PATH environment variable, for example?
-
Hmm I'll try adding it to the PATH xD
EDIT: that didn't work

No, that's not what I meant! I meant, have you done before? Or have you installed some program that did?
-
It's not corrupted because it's a clean install
-
-
already did that.
@TMcSquared
Best guess is that it gets wrong QtDLLs maybe via
path. -
My PATH variable has zero Qt paths in it. even after a clean install.

@TMcSquared
I have no idea then.
last test
can you start with
qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
from shell and see if still crash ? -

Hi,
Then it sounds like a graphic driver issue then. Are you sure there wasn't any modification in that regard on your machine ?

@TMcSquared
You could check whether Windows Update snuck in and did anything since it last worked... :) -
That's completely possible, thanks for your guy's help!
@SGaist I have no idea, it quit working while I was logged in. -
Hi all. Sorry to revive this topic but this problem has occurred to me as well but on an application I wrote for a client. The application was running fine. Then it crashed (just like @TMcSquared ) and hasn't opened since.
My access violation is in theQtWidgets.dllmodule.Any clues? (i don't have the welcome/QmlDesigner/etc modules to disable on load as does qtcreatorI)

@nwoki
Hi
Do you use QML?
if yes, could be a driver issue.Do you have data files?
if yes, it could be damaged data files crashing app on load.It could be client installed other app using Qt dlls and now your app finds the wrong version of Qt dll.
Buts its nearly impossible to guess on without far more concrete information :)

Hi
Do you use QML?
if yes, could be a driver issue.This is reproducable only on the client pc. Any way I can debug this?
Do you have data files?
if yes, it could be damaged data files crashing app on load.Cleaned and still no dice
It could be client installed other app using Qt dlls and now your app finds the wrong version of Qt dll.
No other Qt applications are installed
Buts its nearly impossible to guess on without far more concrete information :)
Any idea on how I can help gather more info for furthur debugging?
