Hi



I am running IPSP sample app using qemu_86 (on master branch).

I have enabled following to detect stack corruption.



+CONFIG_DEBUG=y

+CONFIG_STACK_USAGE=y

+CONFIG_STACK_SENTINEL=y



This results in stack check error.

I tried attaching gdb, but the qemu itself terminates resulting on closure
of debug connection



Can someone give me pointers how to debug the same?
