The problem here is the quote mark is for English's possessiveness rather than a quote but the error message format detection is too simple so it warns which causes -Werror to fail.
Committed as obvious after a quick build. gcc/ChangeLog: * tree-cfg.cc (verify_gimple_assign): Remove quote mark to shut up the warning.
