[Vol-users] stack & heap

Hi guys, I'm trying to find out the addresses of the memory pages of a target process that are used as stack and heap on Linux. (Precisely, I would like to have the output which can be seen in /proc/<pid>/maps for a target process) Unfortunately, the command linux_proc_maps is not working, I always get a segmentation fault, although I tried different kernels as well as Linux setups (Ubuntu) - it's just not working. Can anyone tell me a setup (Linux & Kernel) in which the linux_proc_maps command works? Or give me a hint how I could figure out these addresses on another way? Thank you!
