6.1.4 Stack Overflow Handling

If a stack overflow is detected, the result will be one of the following:

• Exception STATUS_STACK_OVERFLOW may be raised.
  
  
• The system may transparently extend the thread's stack, reset the TEB stack limit value appropriately, and continue execution of the thread.

Note that, if a transparent stack extension is performed, a stack overflow that occurs in a called procedure might cause the stack to be extended. Because of this, the TEB stack limit value must be considered volatile and potentially modified by external procedure calls and by handling of exceptions.
