Hmmm I'm sorry but I'm failing to find where it is used as a null-terminated string. Everywhere I looked, it's used as a pointer+len, including in the functions above. Unfortunately your fix is not correct, as it forces to modify a purposely marked read-only location and overflows it by one char (to add the zero). And in the case of the sample fetch, the resulting string will be wrong as it will include a trailing zero as part of its value. Where exactly did you face the problem ? I'm pretty sure that it's this specific place which needs to be fixed. Thanks! Willy
