Good afternoon!
I have cross-compiled the webkit with qt-4.6.2.
when i transplant the library to the target platform(SH4,ST7162),It seemly that general qt program run correctly,
but when i try to ran qtlauncher which was compiled with webkit and qt,the system send SIGBUS signal

general information is following:

Program received signal SIGBUS, Bus error.
0x29f4ad7a in WebCore::ResourceLoader::releaseResources() ()
   from /opt/QT/qte-directfb-linuxfb-sh4/lib/libQtWebKit.so.4
   
   
Unaligned userspace access in "QtTestBrowser" pid=1636 pc=0x2a012f6a ins=0x01ce
Unaligned userspace access in "QtTestBrowser" pid=1636 pc=0x29f4ad7a ins=0x5111
Sending SIGBUS to "QtTestBrowser" due to unaligned access (PC 29f4ad7a PR 29f4ac6e)

How can I change the source code to avoid the error message!

Hope to get your reply!

Would it be possible to get a full stacktrace for the Bus error ? Thanks.
