Clang Flag: -Wdelete-incomplete / -Wno-delete-incomplete

-Wno-delete-incomplete is a compiler flag in Clang designed for controlling specific warning messages related to deletion operations on incomplete types. When active, this flag suppresses two main categories of warnings: Attempts to delete an expression with a pointer to a void type. Deleting a pointer to an incomplete type, which might lead to undefined behavior. Developers can deactivate these warnings by using the -Wno-delete-incomplete flag. This feature is particularly useful for suppressing warnings in codebases where such deletion operations are known and intended by the developer, thereby reducing noise in the compilation output.
