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