workaround

This error is usually only a warning, so compiling without too aggressive flags should work and run fine because this part won't be executed in your case. I'm too lazy to turn this into a true compile-time if, so what about the attached workaround? (I cannot check it myself)
Comment 3 MailMr_S 2015-02-18 08:27:51 UTC
Thank you, your patch is working. Btw, it is not only a VS2012 problem. I can reproduce this error with VS2010 and VS2013, too. Which flags should I deactivate?
