[SR-Users] Possible memory leak in parse_pai.c

Hello,

I looked quickly to the core and seems ok, I will check the accounting 
later.

Do you simply account $ai or is any other attribute related to it?

If you have time to test, can you put the $ai in an avp during the 
request processing and account that avp? If the leak is not shown 
anymore in that case, it narrows down a lot where to look at.

Cheers,
Daniel
