Re: Compiling Protocol-Plugin c++ (MinGW)

Hey,

I didn't uploaded the source of my plugin yet. I have to clean up the 
code first (some password-stuff and so on), I might be able to do it 
tomorrow. But I can show you the reduced cpp I've written which causes 
excactly the same issue. You can find it here: http://pastebin.com/WbNy1nMr
When I compile it with gcc in c-mode it works fine, but with g++ it 
causes the described issue.

Here is the backtrace after the first 2 "warnings":
(22:18:07) wpurple: wpurple_cleanup
(22:18:08) winpidgin: winpidgin_cleanup
warning: Invalid parameter passed to C runtime function.

warning: Invalid parameter passed to C runtime function.

After the next 2 "warnings" it ends with code 03.

Best regards,
