           Summary: Build failure with GCC 12: no matching function for
                    call to 'end(LChar [7])'
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK

Next challenge in attempting to build with GCC 12: something is wrong with IntegerToStringConversion.h, and it's unclear how to fix it. I'll need to try a few more things....
