Description
In ROOT 6.14 there seems to be a regression with ROOT::RDataFrame with respect to ROOT::Experimental::TDataFrame in 6.12 when defining columns of custom types in code that is compiled and linked against ROOT, as opposed to run as a macro.
With 6.12.04 the test given below passes:
$ sh test.sh 6.12.04

|
Info in <TUnixSystem::ACLiC>: creating shared library /tmpdata/olupton/ROOT-problems/180821-RDataFrame/./test_cpp.so
|
While with 6.14.00 it fails:
$ sh test.sh 6.14.00
|
