[Linphone-developers] About Memory Leak because of osip_transaction_free()

[远方]

Hello,everyone！I saw many people talked about memory leak because of osip_transaction_free() before ,but nodody offered a complete solution on this problem.

 

Aymeric MOIZARD have said： 

****************

You cannot call osip_transaction_free INSIDE cb_kill_transaction.
You  must call it right after the complete execution of the event
list. (the *_execute methods)

In case you call osip_transaction_free within the callback, if there
is 2 events in the transaction queue, the program wil crash. Such
behavior will rarely happen in common situation, but will often happen
under heavy load or for a server based on osip.

I did as Aymeric MOIZARD have said ,but my program crash because of a segment fault occured.Here is my code

*********

 

while (1) {
  osip_timers_ict_execute(osip);
  osip_timers_nict_execute(osip);
  osip_timers_ist_execute(osip);
  osip_timers_nist_execute(osip);

  osip_ict_execute(osip);
  osip_nict_execute(osip);
  osip_ist_execute(osip);
  osip_nist_execute(osip);

  osip_retransmissions_execute(osip);
  osip_release_terminated_transactions(osip->osip_nist_transactions);

 

 // in osip_release_terminated_transactions,i called osip_transation_free and encountered a seg-fault

Thank you for your any help!
