9.3.11 --stackguard size

Set stack guardband to size bytes (default=16).

By default a portion of the physical stack is reserved for a guardband.

The stack guardband ensures that enough stack space is available to process a stack overflow exception. The default value (16 bytes) was chosen to handle the worst-case scenario, and guarantees that an exception handler can be invoked. This option can be used to reserve additional stack space for exception processing, or to reduce the guardband size, freeing up additional memory for the stack.
