Error when trying to write multiple row groups and declare column writer (compile passes tho running into mem mapping issue)

I've been trying to do something like write several int/double columns, yet the second declaration of writer of the same type using next column crashes.

eg. say I have [int64.int64.int64,...double,double]

for (int __c = 0; __c < #columns; __c++)
{
    if (type == int64)
    {
        parquet::Int64Writer* int64_writer = static_cast<parquet::Int64Writer*>(rg_writer->NextColumn());
    }
    else if (type == double)
    {
        parquet::DoubleWriter *double_writer = static_cast<parquet::DoubleWriter *>(rg_writer->NextColumn());
    }
}

I've been looking through the examples in parquet-cpp repo but could not find a fix (or similar example).
