: : Running with efence, I got segfault. Using free()d memory. : : #0 0x0000555555637dd8 in silc_client_command_call (client=0x2b7484245fc8, : conn=0x2b749dac4f70, command_line=0x2b75291f6fe4 "JOIN ipv4 -founder -auth") : at command.c:495 : #1 0x00005555555da4af in silc_queue_command_call (client=0x2b7484245fc8, : conn=0x2b749dac4f70, command_line=0x2b75291f6fe4 "JOIN ipv4 -founder -auth") : at silc-cmdqueue.c:129 : This is because the previous line silc_fsm_start_sync(&cmd->thread, command->command); not only executes the command but finishes the command too by the time the function returns. Two fixes possible: don't access cmd->cmd_ident but save cmd_ident to temp variable or use silc_fsm_start which is not synchronous. The first reported crash seem not be related to this. It appears to be double free.
