Additional info:
I took a look at the source code on sourceforge. This project seems to be in an unfortunate state of non-maintenance, at least as far as I can tell from Googling it. However, somebody has made a patch to fix this. Basically, va_arg is being used wrongly. This is the patch and when I apply it on the source code I got from SF, it works:
