How to settle SIGBUS error???

[grachel]

I encountered a SIGBUS error when I run a phoneMe advanced program on eCos platform.Because eCos only support one process,I can't kill the process which encounters the SIGBUS error.Thus,this process will continue reporting the "Process #42 received signal 10, suspending" over and over again.Then, how should I do to settle this???Anyone can help me ?????

Obviously you need to find out why it is accessing memory that does
not exist. Quite likely this is a null point dereference, or maybe you
have overrun your stack. gdb should help you debug your code. Are you
on an ARM? It could also be you are doing none aligned access.
