SIGBUS when executing native code in real hardware

[hongxue.ren]

Hi all:
    I compiled android-qt, and ported a qt program named htmlviewer.
    The htmlviewer was compiled to a shared library, and another Java Application calls the lib through JNI.
   
    The application runs well in emulator, and can load html files normally.
    However when it runs in real hardware platform(cpu: Marvell pxa310), some html files can load normally,
    and others load failed which SIGBUS signal has received after font loaded.
   

    The strace log section as follow:
