Can you try PHP 7.1? As far as I'm aware of, PHP 7.2 is still not fully supported.

Same error with PHP 7.1.14 and PHP 7.0.25

Is there any chance you could find out what the full query is that causes the error? (option (option_name,option_value) VALUES (?,?)) ? Are you using any custom or 3rd party plugins?

Actually browsing through the code do you see this in the system check?

Having only Standard Addons, disabled all with "example" in name and Ecommerce.

I had this both addons, too. But disabling them together doesn't change anything

With Matomo 3.4.0 it's still there for me. Same error message and no PHP errors.
PHP-Version: 7.2.3

Guess I found the file where it stands.
plugins/Diagnostics/Diagnostic/LoadDataInfileCheck.php

At line 40 there stands following:

        $optionTable = Common::prefixTable('option');
        $testOptionNames = array('test_system_check1', 'test_system_check2');

        $loadDataInfile = false;
        $errorMessage = null;
        try {
            $loadDataInfile = Db\BatchInsert::tableInsertBatch(
                $optionTable,
                array('option_name', 'option_value'),
                array(
                    array($testOptionNames[0], '1'),
                    array($testOptionNames[1], '2'),
                ),
                $throwException = true,
                $charset = 'latin1'
            );
        } catch (\Exception $ex) {
            $errorMessage = str_replace("\n", "<br/>", $ex->getMessage());
        }
