, could you please PR the patch to 8.0.4 seed branch if the issue is present there?

The warnings:

  • In 5.5 and 5.6, about the register keyword. This was fixed shortly after opening the 5.7 branch

  • In 5.7, about using different enum values than the type of the variable in a switch, for some reason, only in the release build

The error:

  • there is an implicit narrowing cast in a constant expression when using the my_offsetof macro, which was fixed shortly after opening the 5.6 branch
