Cling

[code]$ root -n

root [0] int step = 10
(int) 10
root [1] step
(int) -74889133
root [2] int stp = 10
(int) 10
root [3] stp
(int) 10
root [4]
[/code]

global variable name step can not be used with any type, int, double, std::string…
i checked the name “step” doesn’t show up in .g output, and i can define local name step within a function. what kind of bug is it?

On mac with a more recent ROOT version it works fine:

$ root
