Hi, sorry about the problems. It was related to building on 32 bit. I released 1.4.1 which builds on amd64 (with the -m32 flag) and also fixes a logic error in a test plus a formatting issue in the help text.
To prevent this from happening in the future, I plan to add 32 bit building on the continuous integration setup on github. Please find it at https://rdfind.pauldreik.se/rdfind-1.4.1.tar.gz Thanks, Paul
