433 [AS] Note: sometimes, the sscanf() function is used to parse the input
434 into a fixed-size buffer. Because of this, we must be prepared to
435 receive strings as long as the size of the input buffer, which is currently
436 set to 4K for Windows and 8K for the rest.
437 So, we must either allocate sufficiently large buffers here, or
438 reduce the size of the input buffer in the input reading part.
