255 - _alloca indicates failure by raising a stack overflow exception.
Recommended Fix: Consider using an exception handler.

This warning indicates that a call to _alloca has been detected outside of local exception handling.

_alloca should always be called from within the protected range of an exception handler because it can raise a stack overflow exception on failure.

Example

Defective Source

_alloca(10);

Corrected Source

__try {
    _alloca(10);
} __except(GetExceptionCode() == STATUS_STACK_OVERFLOW) {
    _resetstkoflw();
}
