Drouting crashes when selecting next gateway. Did a little investigation, and FWIW the next gateway's carrier status is disabled but the carrier's only gateway is enabled. Looked at the backtrace of the core dump, and found that it crashed while comparing two strings on get_gw_by_id called by use_next_gw. The strings compared were apparently GW ID strings.
I attached the GDB btfull logs (replaced some sensitive info with dummy text) for reference. Take note that 'dont optimize' flag was not set so some of the values were optimized and the crash happened randomly so I can't actually reproduce the crash.
