Can't compile on CentOS 6.6

I'm getting the following errors (gcc 4.4.7):

Sorry for the delay, I missed this issue...
This is a compilation error I haven't encountered before yet and which I can't reproduce locally. I tried to commit a more explicit cast that should fix this hopefully. Can you try the latest version in this git master branch?

Closing this issue due to no activity in a long time, and CentOS 6 being too outdated in the meantime (use CentOS 8).
