Created an attachment (id=90542)
 --> (https://bugs.webkit.org/attachment.cgi?id=90542&action=review)
the backtrace of callstack.

I have got an unaligned access error with browser application (stored in demos directory) on my sh4 board (linux kernel).

Actions :
- installer qt-everywhere-opensource-src (4.7.2)
- Compiled qt-everywhere-opensource-src with STlinux 2.3 toolchain in debug mode (qtwebkit-debug) (=> for SH4 board)
- run the "browser -qws" app from "demos" directory

I got the following error :
Unaligned userspace access in "browser" pid=6590 pc=0x2a1313c0 ins=0x6112

The crash is systematic. I do not edit the source code.

I use QTWebkit 2.0.
