In the process of writing this email I've noticed that wptr is initialised to NULL. Is there any case where that line might be reached without changing wptr's value first? It might be warning you that you're possibly going to decrement a NULL pointer. -1 is rarely going to be a valid memory address...
No, there's a great deal of code between the two points, including initialising wptr to a valid C string.
Both you and Michael Ash point out that the warning is probably erroneous, and now I understand what it's trying to tell me, I agree - there's no real problem here, which is good, as I've used this code without any problem for well over a decade in several projects.
