Hi Qt
I am hoping to get some help / advise on this.
We are using Qt5WebKit in our project, it is almost identical to the FancyBrowser example.
I have executed this example with releases
5.3.1
5.3.2
I browse to the website “ndtv.com” (known to crash) and wait for the page to load. If it has not crashed at this point, click the movies link and wait for it to load.
The problem is the issue is intermittent, it might crash, it might not.
I thought this was an issue in our module so I enabled full page heap checking
http://msdn.microsoft.com/en-us/library/windows/hardware/ff543094(v=vs.85).aspx
gflags /p /enable fancybrowser.exe /full
gflags /i fancybrowser.exe +hpa
gflags /i fancybrowser.exe +02000000
This always point to a memory issue within Qt5WebKitd! or Qt5WebKit
Although the stack traces are always slightly different, they always point to a memory operation.
In the trace below, I compiled the example FancyBrowser and executed it on windows 8 32 bit with full page heap checking.
I think there is a heap corruption bug in Qt5WebKit and it only shows up randomly.
If you enable full heap checking, it is possible to see it all the time.
I am still fairly new to QT so feel free to double check anything with me.
I am currently using QT version 5.3.2 and visual studio 2013 express.
Although I have seen the same issue with vs 2008.
Thanks ( post limited to 6000 chars, I will copy the stack trace later)
