> 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 1.6.1.0, 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.
