[Jamvm-general] QT-Jambi sigsegv at startup issue.

[Xerxes R. <xe...@za...>]

Hi
I am testing JamVM git head + OpenJDK 6 1.11.1 against the qt-jambi framework on a 32bit x86 machine:

http://qt-jambi.org/ - Qt Jambi 4.7 beta this is the current actively maintained community supported version.
http://qt-project.org/wiki/Qt_Jambi - Qt Jambi 4.5.2_01. This is last version by the Qt team.

Testcase:
wget http://downloads.sourceforge.net/project/qtjambi/4.7.0-beta2/qtjambi-linux32-community-4.7.0-beta2.tar.gz
tar zxvf qtjambi-linux32-community-4.7.0-beta2.tar.gz
cd qtjambi-linux32-community-4.7.0-beta2
./qtjambi.sh

the ./qtjambi.sh launches:
/usr/bin/java -jamvm -cp ./qtjambi-util-4.7.0.jar:./qtjambi-linux32-gcc-4.7.0.jar:./qtjambi-examples-4.7.0.jar:./qtjambi-designer-4.7.0.jar:./qtjambi-4.7.0.jar: com.trolltech.launcher.Launcher

I get an immediate crash during qt-jambi startup while using jamvm in contrast both cacao and hotspot work to launch these qt-jambi examples.
I hit the same issue for both the 4.7 and 4.5.2 version.

Program received signal SIGSEGV, Segmentation fault.
