I actually got to the bottom of this and it was a pretty silly mistake. The
problem was in string conversions:
My message callback looks like this:
messageHandler(const RWCString& buffer_)
and the parse method signature is this:
ParseFromString(const string& data);
So to convert between the two string types I was calling buffer_.data()
which returns the char * and then std::string was created from that. Now it
looks like the string representation of the GPB probably has something like
\0 in it which caused the std::string to truncate it. Once I switched to
the RWCString::std() function to do the conversion it all worked out fine.
