> we log an invalid file version string. Whatever 4 bytes that that pointer
> points to will end up in the profile. These can be non-ascii characters, thus
> potentially breaking tools that parse the profiles and expect their content
> to be plain text. We should either remove the bytes from the message, or
> escape them as hex.
