Description

Neil Mitchell has developed a technique for detecting space leaks and successfully used it to find space leaks in several programs.

Maybe we should try using this technique on stack!?

Contributor guide

Research direction
Familiarize yourself with Neil Mitchell's space leak detection technique, then apply it to the stack codebase. Set up a profiling environment, run stack with heap profiling, and analyze the output to identify potential space leaks. Look for functions that retain memory unnecessarily.
