Intermittent crashes printing from Mac OS X using Qt 4.8.1

[AndyBrice]

I am getting some crashes printing or exporting PDFs from the Mac version of my product. The users tell me the crashes are intermittent (i.e. will crash sometimes, but not others). No problems with the Windows version.

The crash stack traces look like this:

Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

They all seem to involve a call to PMGetAdjustedPageRect. I'm not sure if it is related to this bug:
https://bugreports.qt-project.org/browse/QTBUG-21576

Is anyone else seeing something similar? Any idea of what the problem might be?

best regards

I'm trying to use Qt 4.8.1 on Windows 7 with Illustrator CS 5. When I quit Illustrator, the application crashes. If I remove the instanciation of the QApplication, Illustrator closes properly.



Is it possible to share some small example which runs on Windows and MacOS X ?
