Building O2 fails in 'unittest_Logger.cxx'

Dear Experts

I am trying to build O2 in a Mac (10.14.6). I tried to install a fixed version
(nightly-20200122) but it did not work. See:

Not even after updating again alidist. So I decided to try to install the latest version.
I did:

cd ~/alice/alidist
git checkout master
git pull --rebase

cd ~/alice/O2
git checkout dev
git pull --rebase

cd ~/alice
aliBuild build O2 --defaults o2 -z O2-20200216

and now the building crashes at unittest_Logger.cxx. The full log is at:

https://physics.fjfi.cvut.cz/~contrgui/tmp/log_O2_20200216

any help is greatly appreciated

thanks
