Crash when creating RDataFrame graph

Hello,
I still can’t figure out how to reproduce it with a simple code, but when writing an example, I notice some strange features from the graph -
test3.C (3.2 KB) testtree2.root (6.8 KB)
it runs on a simple tree with float and vector<float> branches
it produces
new
which is what I wanted to achieve, however when

  //latestDF = std::make_unique<RNode>(latestDF->Define("r42",[](){return 42;}));

is uncommented, the graph changes to


However, the output root stays the same/the v_float part gets filled.
I also noticed when I define multiple columns

latestDF = std::make_unique<RNode>(latestDF->Define("A",...);
latestDF = std::make_unique<RNode>(latestDF->Define("B",...);
latestDF = std::make_unique<RNode>(latestDF->Define("C",...);

this gets plotted as T->C->B->A instead of T->A->B->C?


test4.C (751 Bytes)
