Hi all,

I'm trying to run a browser arora (http://code.google.com/p/arora/) on lpc3250.

I have configured qt 4.8.2 with following parameters:
./configure \
    -debug \
    -shared \
    -embedded arm \
    -xplatform qws/linux-arm-vfp-g++ \
    -little-endian \
    -opensource \
    -confirm-license \
    -no-cups \
    -no-qt3support \
    -openssl \
    -no-opengl \
    -no-freetype \
    -qt-gfx-linuxfb \
    -make tools \
    -make plugins \
    -webkit-debug \
    -iconv \
    -qt-kbd-tty \
    -qt-kbd-linuxinput \
    -qt-mouse-linuxtp \
    -qt-mouse-tslib \
    -qt-mouse-linuxinput \
    -I/home/alexanis/src/ltib/rootfs/usr/include/ \
    -L/home/alexanis/src/ltib/rootfs/usr/lib/

But when I try to launch the browser it failed with illegal instrutstion.

I run it in gdb and get a backtrace
