[Bug c++/44473] New: iterators already defined for std::vector when using std::decimal

["rmlong at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

If checking empty then attempting to push back the following errors are
reported:
main.s: Assembler messages:
main.s:2236: Error: symbol
`_ZNK9__gnu_cxx17__normal_iteratorIPDfSt6vectorIDfSaIDfEEE4baseEv' is already
defined
main.s:2542: Error: symbol
`_ZN9__gnu_cxx17__normal_iteratorIPDfSt6vectorIDfSaIDfEEEC2ERKS1_' is already
defined

Preprocessed file: http://dl.dropbox.com/u/2280/main.ii
Example code:
#include <decimal/decimal>
#include <vector>

int main()
{
    std::vector<std::decimal::decimal32> vec;

    if (vec.empty())
    {
        vec.push_back(std::decimal::decimal32(0));
    }

    return 0;
}
