terminate called after throwing an instance of 'std::error_code' when read_row

[fs273]

I just started using this library, version 2.3.0, currently only using reader's read_row in a simple loop to read each line and print out, it can handle 99.99% of csv files correctly.
But there are some files reading rows will throw terminate called after throwing an instance of 'std::error_code' error, directly resulting in Aborted(core dumped), After pop_front:

csv-parser/single_include/csv.hpp

Line 7628 in 9f8a721

row = this->records->pop_front();

, the program aborts. After two days of testing, I have found this occurs only during execution, and reproduce every time it encounter a fixed line in the csv file, but it is ok when I debug it.
I realized it might be a multithreading issue, I add std::this_thread::sleep_for(std::chrono::milliseconds(1)); after

csv-parser/single_include/csv.hpp

Line 7613 in 9f8a721

this->read_csv_worker = std::thread(&CSVReader::read_csv, this, internals::ITERATION_CHUNK_SIZE);

Now it's fine to read all csvs.
But I still don't understand the cause of this problem. Why is the read_csv thread not active? Does pop_front cause core dumping before read_csv thread is ready?
Sorry I couldn't provide the csv that would reproduce the problem.
