           Summary: g++ 3.x outputs wrong mangled names for some "global
                    constructors keyed to"
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: carlo at alinoe dot com
                CC: gcc-bugs at gcc dot gnu dot org

The mangled names of some "global constructors keyed to" symbols
have wrongly an "anonymous namespace" extention appended.

Examples that I found in the distributed libstdc++ are:

# nm /usr/local/gcc-3.0.4/lib/libstdc++.so | grep GLOBAL__I_
0004dd90 t
_GLOBAL__I__ZStorSt12_Ios_IostateS__usr_src_gcc_gcc_3.0.4_libstdc___v3_src_locale_inst.cc5yFzLb

This should be

_GLOBAL__I__ZStorSt12_Ios_IostateS_

# nm /usr/local/gcc-3.1/lib/libstdc++.so | grep GLOBAL__I_
0005fd62 t _GLOBAL__I__usr_src_gcc_gcc_3.1_libstdc___v3_src_ext_inst.ccEupxgb
0005f87a t
_GLOBAL__I__ZStorSt12_Ios_IostateS__usr_src_gcc_gcc_3.1_libstdc___v3_src_locale_inst.cchLn6gb

The first one is utter nonsense, it can not be determined
what symbol that is supposed to refer to!
The second one should be

_GLOBAL__I__ZStorSt12_Ios_IostateS_

# nm /usr/local/gcc-3.1.1/lib/libstdc++.so | grep GLOBAL__I_

These are three times total nonsense.
