Description
Reading a TFormula from a ROOT file shows the following symptom:
Expression passed to Cling:
[73381]: Double_t TFormula____id8411857145669054181(Double_t *x){ return 1/(TMath::Gamma(1.64366)*32.2452)*std::pow(x[0]/32.2452,0.643656)*std::exp(-x[0]/32.2452) ; } |
[73381]: std::exp is unknown. |
[73381]: std::pow is unknown. |
[73381]: polya : 1/(TMath::Gamma(1.64366)*146.016) *std::pow(x/146.016, 0.643656) *std::exp(-x/146.016) Ndim= 1, Npar= 0, Number= 0 |

This bug appeared after our recent switch to ROOT 6.14.4 on MacOS 10.13.6. There was no problem with the same code before. The problem appears only at reading not at writing.
Attaching the problematic file. Saying root
`root test.root` and inspecting the formula in the TBrowser also does not work:
Error in <TFormula::Eval>: Formula is invalid and not ready to execute

std::exp is unknown.

std::pow is unknown.
