Looking over a 32-bit build log from Debian, to check for potential issues with 32-bit build:

/<<PKGBUILDDIR>>/Source/WebCore/PAL/pal/FileSizeFormatter.cpp: In function 'WTF::String fileSizeDescription(uint64_t)':
/<<PKGBUILDDIR>>/Source/WebCore/PAL/pal/FileSizeFormatter.cpp:36:31: warning: format '%tu' expects argument of type 'unsigned ptrdiff_t', but argument 2 has type 'uint64_t' {aka 'long long unsigned int'} [-Wformat=]
         return String::format("%tu bytes", size);
