VLD shows that PHP thinks line 45 has some code:

44 9 ZEND_VERIFY_ABSTRACT_CLASS $0
45 10 > RETURN 1

Trying to find the 0 now...

i suggest checking what token_get_all() returns about line 45 (if anything)

(btw, at least atm, the link to sample file is 404)

I have not found the 0 yet, but now the example script is gone... suspending for now.

I am seeing the issue with line number 0 in my https://github.com/sebastianbergmann/money for the src/Money.php file.

However, outside of PHPUnit and this specific test suite I cannot provide a short reproducing script other than the following:

<?php
require '/usr/local/src/money/src/autoload.php';

use SebastianBergmann\Money\Money;
use SebastianBergmann\Money\Currency;

xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
new Money(0, new Currency('EUR'));
$data = xdebug_get_code_coverage();
xdebug_stop_code_coverage();
var_dump($data);
?>

This prints, among data for the other files loaded, the following:

'/home/sb/test.php' =>
array(3) {
[0] =>
int(1)
[8] =>
int(1)
[9] =>
int(1)
}

Is this specific code coverage related issue still cause a problem for you?

No.

Okay - let me close this then.
