#17636 closed bug (fixed)

fgetws function crashes the program if less than num - 1 characters are present in the current line

Description

If the current line being read by fgetws has less than num - 1 characters present in the current line (where num is the number of wide-characters requested in the 2nd argument) and an additional line comes after it, fgetws will cause the program to crash. This doesn't happen under Linux/macOS/Windows at all.
