During compilation of libstdc++ for i686-pc-mingw32, I noticed this warning:
../../../../gcc44-svn/libstdc++-v3/src/atomic.cc:83: warning: 'd' is used uninitialized in this function ../../../../gcc44-svn/libstdc++-v3/src/atomic.cc:83: note: 'd' was declared here Notice the 'is used' and not 'maybe used'. The warning was noted with gcc shapshot r149016 from gcc-4_4-branch. Does not happen for x86_64-pc-mingw32. The toolchain was compiled against mingw-w64 header-set and crt. -- Summary: atomic.cc: 'd' is used uninitialized warning Product: gcc Version: 4.4.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: sezeroz at gmail dot com GCC target triplet: i686-pc-mingw32 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40654
