>Description:
The code submitted, when compiled with -frepo option,
causes numerous iterations of:
 collect: recompiling frepo.C
 collect: relinking
before failing with an undefined symbol.
The source to the problem is in the use of the unnamed
namespace for the structure definition.
The example code uses an stl list, but changing it to
a vector or deque shows equivalent results.
>How-To-Repeat:
#include <list>

namespace {
    struct data {
        int v;
    };
}

int main(int,char **)
{
    std::list<data> llist;
    return 0;
}
