------- Comment #5 from jakub at gcc dot gnu dot org 2009-02-17 07:14 ------- The reason it got reported to me is package(s) failing to build with -Werror, nothing wrong in the application code (the bug is supposedly either in the aliasing code, FE or libstdc++-v3 headers) and no obvious way to work around the warning.
