Possible bug in ncl 6.1.2 when accessing part of character array ?

Hi NCL developers,
I think there is a bug in ncl/6.1.2. I am simply accessing part of a character array, and i get a different answer if i use 6.1.2 as compared to 6.0.0. Can others please confirm if they can re-produce this (or it's just me).

Code:
some_char= tochar("abc_def_ghi")
print(some_char(dimsizes(some_char)-4:dimsizes(some_char)-2))

Outputs:
[z3381484@monsoon Soil-Albedo-Scripts]$ which ncl
/share/apps/ncl/6.0.0/bin/ncl
[z3381484@monsoon Soil-Albedo-Scripts]$ ncl test_char.ncl
