Hi Orion,
I am afraid this is impossible to avoid. Qt devices rely on a QCoreApplication,
which is basically an event handling loop, or a QApplication, which is a class
derived from QCoreApplication that handles loops in a graphic environment (X).
I could have chosen to instantiate a QCoreAppli

Hello all,
Just for information, the Qt driver runs fine (but not valgrind-clean) on
Mandriva 2009.1 64. Summing up, the segmentation fault issue occurs on:
- Ubuntu 9.04 64
- OpenSuse 11.1 64 (Qt 4.5 only, Qt 4.4 is fine)
But not on
- Mandriva 2009.1 32 or 64 (Qt applications not valgrind clean)

I'm trying to find out a cause for the crash in examples/c/test_plend with the

- works fine on Qt 4.5.x (32 bit)
- corrupts something that ends up crashing getenv() with Qt 4.5.x (64

First of all, sorry for the previous empty e-mail!
You will find attached a patch for the Qt driver. The main feature is a better
implementation of flushing, resulting in x17c running about as fast as the
other drivers (11 to 13 seconds on my system depending on anti-aliasing, where

Just for information, there was indeed an issue with superscripts/subscripts in
the Qt driver (floating point precision issue on a test), which was fixed in
the latest patch: so this was intentional and not just a side effect of
something else :)

Here is a patch for the Qt driver. It fixes a couple of minor bugs, and it also
