keep_alive_timer_cb crash on IOS

Seem to be getting on iPhone X, doesn't happen on other iPhones as far as I can tell.

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000048

with the callback keep_alive_timer_cb. Do you have any idea what could be causing this? @datso, seeing as keep_alive_timer_cb isn't directly in your repo but is in PJSIP?

EDIT

If any one else is having this same issue. You can disable the keep_alive_timer by adding

 cfg.ka_interval = 0;

After

        pjsua_acc_config cfg;
        pjsua_acc_config_default(&cfg);

in PjSipAccount.m
