You can use enable_stack_check/disable_stack_check to selectively
stack-check functions:

   enable_stack_check ();
   define foo() { ... }
   disable_stack_check ();
   
   define bar() { ... }

In this case, foo would get checked but bar will not.

You should try to minimize the use of such constructs.

All I can suggest is that you selectively use calls to
enable_stack_check/disable_stack_check.  Also you see the same line
appearing in the stack check output over and over again, and you
believe that it is ok, then you should rewrite it, e.g,.

   do_check ();
   if (do_something ()) ...

or

   do_check ();
   variable status = do_something ();
   if (status) ...

Good luck,
