With current git-HEAD, this code snippet extracted from the std.exception unittests:

T ifThrown2(E : Throwable, T)(T delegate(E) errorHandler)
{
    return errorHandler();
}

unittest
{
    static if (__traits(compiles, ifThrown2!Exception(e => 0)))
    {
    }
    static if (__traits(compiles, ifThrown2!Exception(e => 0)))
    {
    }
}

compiled with "dmd -m64 -unittest -main" results in:

test.obj : fatal error LNK1179: invalid or corrupt file: duplicate COMDAT
'_D4te
st15__unittestL32_5FZv17__T0TC9ExceptionZ0MFNaNbNfC9ExceptionZi'

This does not happen with dmd 2.063. The code actually does not compile, so it seems that broken code is emitted to the object file.
