Package: libstdc++-4.8-dev
Version: 4.8.2-15
Severity: important
File: libstdc++
Tags: upstream

Dear Maintainer,

-static-libstdc++ does not seem to be working anymore.
Consider this following test application:

---------------------
#include <iostream>
#include <string>

int main()
{
  std::string s;
  if (s.empty()) { std::cout << "String is empty!" << std::endl; }
  return(0);
}
---------------------
g++ -Wall -o test test.cpp -static-libgcc -static-libstdc++

"test" here should not contain any references to libstdc++ symbols as it is being linked statically, however, "objdump -T test" contains the following:
00000000006915c0 u    DO .bss   0000000000000020  Base        _ZNSbIwSt11char_traitsIwESaIwEE4_Rep20_S_empty_rep_storageE
0000000000691600 u    DO .bss   0000000000000020  Base        _ZNSs4_Rep20_S_empty_rep_storageE

These are both symbols from libstdc++ that should have been staticaly linked, yet they are now undefined, and indeed, this binary will not run on a system without a sufficiently up to date libstdc++ installed.

The same problem occurs with:
clang++ -Wall -o test test.cpp -static-libgcc -static-libstdc++

So the problem seems to be more of an interaction with libstdc++ and the linker than the compiler in question.

An older Debian setup I have back when GCC 4.6 was current does not exhibit the problem here.
