fixed in the meantime with this local edit... but i'm sure there's a better way

Having the same problem here on a Ubuntu 20 build with clang 6.0 on an rpi. Is there a branch with this local patch available? I am running into the problem while trying to use a docker container to automate the build process for distributable debs.

Hi. The problem is in external library referred in git submodules - where we are currently referring an old version without fix. We will update submodules to latest versions of external dependencies...

[johniez]

It should be fixed in master branch.
