checkinstall freezes at "Copying files to the temporary directory..." when building vim8

I'm having a very strange problem with checkinstall when trying to build vim8. Here's what I did (although probably irrelevant): - Cloned from vim8 git source - Ran configure & make --enable-gui=auto. No problem. Then I ran sudo checkinstall, the installation and man page generation progressed all right, but somehow the program got stuck at the last steps: Some of the files created by the installation are inside the build directory: /mnt/C/XXXX You probably don't want them to be included in the package, especially if they are inside your home directory. Do you want me to list them? [n]: y Should I exclude them from the package? (Saying yes is a good idea) [y]: y Copying files to the temporary directory... I also tried: checkinstall --install=no, which didn't work either. Anyone has any ideas? Thanks!
