optimize error? (cargo release build is failed, cargo debug build is successed)

[takurx]

It's strange. Is it might be depend to be update library, crates.io? Thanks.

Could you try again, I just updated a lot of dependencies.

I should try it on RPi.

[takurx]

Surely. Excuse me, it is specific RPi's problem. I have checked no problem on laptop PC (Ubuntu 18.04.2 LTS, intel core i7). Thanks.
