Malloc in ROOT

ROOT
1

Hi ,
I am trying to run the attached code in root (4.04). Its crashing when I am trying to access the 3d array from a function. This output is pasted below.

But the entire program runs smoothly if I just compile it using gcc and dont use root.

. output >>>>>>>>>>>>>>>>>>>>>>>>>>

Hi,

I can reproduce this. Is there a chance that you can survive with compiling your macro for now (as in .x test.C+)? This patch requires a bit more work, and I would prefer to fix this in a few months, when we have a new reflection database in CINT.

Axel.

Hi Axel,
thank you. Yes, I have found an alternate way of working with this. Once the fix is in, I will get the new version of root.
