Error in while debugging in xutility

[MattyGroGy]

When i compile my code everything is fine, but after that when i try to create message i get error in xutility here:

this is my proto:

this is code for message: (blue arrow is where is when error)

What kind of error message are you getting?

[MattyGroGy]

During boot im doing initialization of my networking manager async (using std async), then when i click on button i call function that makes my message, exact error is 0x00B42F32 in -projectname- 0xC0000005, write access violation (I have my visual studio in czech but i can send you exact photo)

OK, it's hard to say based on that kind of error message but I am guessing that the problem is not related to protocol buffers. My guess is that game->inputReader->wstringToString(pwd).c_str() is returning NULL or an invalid pointer, or perhaps the crash is occurring before msg.set_mail(...) even begins executing. You might want to try logging that string and seeing if it appears to be valid.

I just used some breakpoints and game->inputReader->wstringToString(pwd) is returning valid string, error happens when msg.set_mail(...) is executed

@MattyGroGy The code looks OK so it's kind of hard to tell what the problem is. If you could post a reproducible example then that would help. By the way, what does wstringToString(pwd) return? If it's a std::string then you could set that directly, but if it's something other than a std::string, I wonder if perhaps c_str() is returning a string that's not NULL-terminated and which would therefore be problematic. That is just a guess, though.
