Bandwidth test crashes hAP lite with 6.34.1

Performing a TX bandwidth test through the CLI crashes the hAP lite with RouterOS v6.34.1.
I can reproduce the issue by executing the following command:

/tool bandwidth-test 10.96.88.10 protocol=udp direction=transmit duration=30s

After a few moments, the routerboard will reboot and come back up with the following message in the logs:

system,error,critical router was rebooted without proper shutdown by watchdog timer

Downgrading to RouterOS v6.32.4 solves the issue.
