[Qt] ARM Qt4Pas V2.1 Access Violations

Hello all on the Qt4Pas V2.1 mailing list.

Thank you for the great work.

I have a small problem and cant seem to fix it. I compiled libQt4Pas
V2.1 for i386 and ARM. The examples works 100% on my i386 machine, but
when I compile the project for ARM, it compiles without any problems.
The problem is that when I try to run it on my ARM board (kernel
2.6.33-2) I receive the following errors.

When compiling for GTK2+ it work on both my i386 and ARM computers
without any probelms.

Any suggestions or help would be appreciated. I would email you the
compiled libraries for ARM or if someone has compiled ARM libs, please
email them to me so that I can see if they work for me.

By the way, I'm using the latest svn versions of both lazarus and fpc

Kind Regards
Anton Rieckert
