Bug#409494: Segmentation fault in iconv_open/iconv_close for some encodings in some sequence

[Dmitry-T <dmitry-t@yandex.ru>]

Package: libc6
Version: 2.3.2.ds1-22

iconv_open and iconv_close for some encodings in some sequence causes
Segmentation fault. I`m stable reproduce segmentation fault only with
static linking. Without static linking reproduce error more difficult.
Here is a transcript:

$ cat bug1.cpp
#include <iostream>
#include <iconv.h>

int main( int argc, char* const argv[] )
{
    iconv_t cd;

    cd = iconv_open( "CP1251" ,"UTF-8" );
    iconv_close( cd );

    cd = iconv_open( "IBM866" ,"UTF-8" );
    iconv_close( cd );

    cd = iconv_open( "KOI8-R" ,"UTF-8" );
    iconv_close( cd );

    cd = iconv_open( "ISO_8859-5" ,"UTF-8" );
    iconv_close( cd );

    cd = iconv_open( "CP1251" ,"UTF-8" );
    std::cerr << "UTF-8 -> CP1251 iconv_open() done.\n";

    iconv_close( cd ); // Segmentation fault
    std::cerr << "UTF-8 -> CP1251 iconv_close() done.\n";
}

$ g++ -O0 -Wall -c bug1.cpp
$ libtool --mode=link g++ -o bug1 -all-static bug1.o

$ ./bug1 
UTF-8 -> CP1251 iconv_open() done.
Segmentation fault

I am using:
