Stack check failure with qemu_x86

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?
