Yes, it does, see my example:

| concatenated at runtime).
-Werror=format-security removes the functionality of building format strings
at runtime, and there are legitimate uses for such functionality.
And it has been mentioned elsewhere in this thread that GCC doesn't even
recognize cases where the format string is constant, but not a string
literal, where it is picked from a list of constant formats, etc.
