|Description:||transmit_refer is used to implement the sip_transfer function on Up calls. It calls sip_refer_allocate without checking to see if there is already a p->refer structure.
Transfers can fail, so this can happen several times in a call.
The only time that this structure is released is when the SIP private structure is destroyed.
****** ADDITIONAL INFORMATION ******
Identified by code reading only and initially on 18.104.22.168, whilst working on ASTERISK-15145, but also present in the current trunk version.
This is on my list for ASTERISK-15145, but we may yet abandon it, so I am recording it as as separate issue. (Also the fix may be obvious to someone who knows the code - my slight concern at the moment is that something may be assuming a clean structure.

It looks like this leak is possible, so I've posted a patch to [review board|https://reviewboard.asterisk.org/r/4160/].
