Description

Currently we only check for the maximum stack size before trying to push an element onto the stack. However, we should also limit the capacity of the internal Vec to prevent any unexpected memory usage.

Contributor guide

Research direction
Examine the stack push function and add a capacity check on the internal Vec before allocation.
