[Qt-interest] Qt 4.7.0 application Segmentation Fault on Mx51

[Manoj Agrawal]

Hello,

I recently upgraded to Qt 4.7.0 from Qt 4.5.3 due to a specific keyboard event issue (I don't get Qt::Key_Enter release) on Mx51. Keyboard event issue got resolved but I got into segmentation fault in libqjpeg.so. My application runs and works fine but crashes at some points with following core dump:

Program terminated with signal 11, Segmentation fault.
#0  0x2ef87958 in ?? ()
   from /root/release_mx51_project/plugins/imageformats/libqjpeg.so

I did some google and found that people have faced similar segmentation faults and resolved using -no-freetype in configuration options. But looks like, my problem is different as it is crashing in jpeg plug-in.

I am using following configuration options
CONFIG_OPTS=-v -confirm-license \
                        -opensource \
                        -debug-and-release \
                        -embedded arm \
                        -platform /qws/linux-x86-g++ \
                        -xplatform /qws/linux-arm-gnueabi-g++ \
                        -little-endian \
                        -openssl \
                        -qt-gfx-linuxfb \
                        -qt-zlib \
                        -qt-libjpeg \
                        -qt-gif \
                        -qt-libtiff \
                        -qt-libpng \
                        -qt-libmng \
                        -fast \
                        -no-dbus \
                        -no-javascript-jit \
                        -no-largefile \
                        -qt-sql-sqlite \
                        -no-qt3support \
                        -no-webkit \
                        -no-cups \
                        -no-mmx \
                        -no-3dnow \
                        -no-sse \
                        -no-sse2 \
                        -no-svg \
                        -no-scripttools \
                        -nomake examples \
                        -nomake demos \
                        -nomake docs \
                        -L$(PROJECT_ROOT)/dist/opt/freescale/bsp/mx51/L2.6.31_10.05.02_ER_source/rootfs/usr/lib \
                        -I$(PROJECT_ROOT)/dist/opt/freescale/bsp/mx51/Linux_2.6.31_SDK1.7/rootfs/usr/include \
                        -I$(PROJECT_ROOT)/dist/opt/freescale/bsp/mx51/Linux_2.6.31_SDK1.7/rootfs/usr/include/openssl

Any pointers on this will be great help. Please let me know if I should also supply g++ and qmake patches, I am applying for this build.

Thanks and Regards,
Manoj
