Segmentation fault with rust

[bWanShiTong]

Sometimes when connecting to Peripheral segmentation fault happens when debugging why, stop reason is signal SIGSEGV: invalid address in function void Bindings::RustyPeripheral::link(SimpleRsBLE::Peripheral& target) in line 129:

* thread #1, name = 'ble-cron', stop reason = signal SIGSEGV: invalid address (fault address: 0x62663433)
