Hello,
with the lastest ROOT version, my subroutine crashes with next error message:
Error in <TH2F:DoProjection>: Histogram with name must be a TH1D and is a TH2F
*** Break *** segmentation violation
My subroutine worked fine with previous version. I do not know exactly what cause crash because if I recompile subroutine, it works without crashing. I can send you my subroutine (it is a bit long)
