You should set *labelPtr to NULL here, since the code below is not guaranteed to assign it. > + } > + > + if (label) { > + /* set new label string */ > + > + if (length >= 0) { > + /* explicit length */ > + *labelPtr = (char *) malloc(length); > + if (*labelPtr) { > + memcpy(*labelPtr, label, length); > + } The length given by the client is not required to include a terminating null-character. > + } > + else { > + /* null-terminated string */ > + int len = strlen(label); > + if (len >= MAX_LABEL_LENGTH) { > + /* An INVALID_VALUE error is generated if the number of > characters > + * in <label>, excluding the null terminator when <length> is > + * negative, is not less than the value of MAX_LABEL_LENGTH. > + */ > + _mesa_error(ctx, GL_INVALID_VALUE, > + "%s(length=%d, which is not less than " > + "GL_MAX_LABEL_LENGTH=%d)", caller, length, > + MAX_LABEL_LENGTH); This error should also be generated when the client specifies an explicit length that exceeds MAX_LABEL_LENGTH.
