死机问题的解决 - 反汇编的应用(1)

某次死机出现如下提示:
o_page_fault() #2: sending SIGSEGV to #UIFrameworkTas for invalid read access from
50fe0ce8 (epc == 00552c38, ra == 005c3d44)
(!) [  492:    0.000] --> Caught signal 11 (at 0x50fe0ce8, invalid address) <--
Aborted

运行
mipsel-linux-objdump -D appCabotCVD > ~/work/scrach.txt
从scrach.txt中找,发现:
5c3d44 在 _ZNDemoApp20CurrentServiceisDataEv内部
552c38在_ZNK19UILegacyServiceList6handleEi中

由此判定DemoApp.CurrentServiceisData调用UI::ServiceListhandle出错
