Nullptr dereference when a null char is present in a proto symbol. The
symbol is parsed incorrectly, leading to an unchecked call into the proto
file’s name during generation of the resulting error message. Since the
symbol is incorrectly parsed, the file is nullptr. We recommend upgrading
to version 3.15.0 or greater.
