Summary0000401: Code Coverage is wrong for if statement
Description
1 <?php
2 xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
3
4 if (false)
5     print '*';
6
7 $codeCoverage = xdebug_get_code_coverage();
8 xdebug_stop_code_coverage();
9

10 print_r($codeCoverage);

This results in

Array
(
[/home/sb/test.php] => Array
(
[5] => 1
[7] => 1
)
)

which is wrong as line 5 is not executed.

Adding braces for the if() block changes things a bit:

1 <?php
2 xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
3
4 if (false) {
5     print '*';
6 }
7
8 $codeCoverage = xdebug_get_code_coverage();
9 xdebug_stop_code_coverage();

10
11 print_r($codeCoverage);

results in

Array
(
[/home/sb/test.php] => Array
(
[4] => 1
[8] => 1
)
)

Unfortunately, this one is not fixable. PHP simply reports no code on line 4:

line # op fetch ext return operands

2 0 EXT_STMT
1 EXT_FCALL_BEGIN
2 BW_OR ~0 1, 2
3 SEND_VAL ~0
4 DO_FCALL 1 'xdebug_start_code_coverage'
5 EXT_FCALL_END

8 PRINT 0000002:0000002 '%2A'
9 FREE 0000002:0000002
