@jellychen , thank you for reporting the issue.

Could you tell me your compiler name and version?

@roopaligalgali , thank you for reporting :)

It seems that suppressing maybe-uninitialized functionality is introduced since 4.7. (I tested 4.7.3 and 4.7.4).

I will update the following version checking code and other the same checking:
