| Summary | 0004604: double free or corruption in social_api:984 | ||||
| Description | When trying to make a --guest-talk to a remote host, gnunet-social crashed in social_api:984 when executing "GNUNET_free (gconn);". I commented the line, then the command runs and terminates safely. The question is, is it okay to just remove that free() call, or have I created a memleak? Or is the same code a few lines above, which does not have that free() call, the correct code which should have been in place for gconn as well? | ||||
