No > declaration in headers, not exported from the shared lib. This one uses > alloca for the same size as __throw_out_of_range_fmt + 104 bytes, but we've > already done the first alloca, so it's (strlen(fmt) + 512) * 2 + 104. There's also __concat_size_t in that file, but it only uses alloca for 3*sizeof(size_t), and that is unnecessary and should be replaced with std::to_chars.
