Running the Following Code with Julia `LibCurl.jl`

```julia
curl_header_list = Cstring[]

    for header in keys(headers)
        value = headers[header]
        item =Cstring(pointer("$header: $value"))
        push!(curl_header_list, item)
    end

    curl_easy_setopt(curl, CURLOPT_URL, "$burl/api/v1/order/bulk")
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, curl_header_list)

    res = curl_easy_perform(curl);

```

We are receiving the following segmentation fault error message:

```julia

Try this code:

```julia
    slist = Ptr{Cvoid}(0)
    for header in keys(headers)
        slist = curl_slist_append(slist, "$header: $(headers[header])")
    end

    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, slist)

```
