is there any way to find the address range of heap and stack allocated to an application in Ubuntu? I hope Valgrind or a plugin of Valgrind can help me but I didn't find it.
On Linux you can inspect /proc/[pid]/maps file containing currently mapped regions to the process. The file also has special sections [stack] for stack of main process, [stack:<tid>] for thread tid stack and [heap] for process heap. For more info, see man 5 proc.
