Incorrect code coverage with switch(true) - line is not covered

[maks-rafalko]

Q	A
php-code-coverage version	5.1.0
PHP version	7.1.0
Driver	Xdebug
Xdebug version (if used)	2.5.1
Installation Method	Composer
Usage Method	PHPUnit
PHPUnit version (if used)	6.1.0

The line of code with switch(true) is not covered in Code Coverage Data. When it has any other condition, like switch($someVar) - it works as expected

I'm not sure this is an issue with code coverage or xDebug, but I don't have enough knowledge to check it.

I have a similar issue in a slightly different setup:

Q	A
php-code-coverage version	5.2.2
PHP version	7.1.9
Driver	Xdebug
Xdebug version (if used)	2.5.5
Installation Method	Composer
Usage Method	PHPUnit
PHPUnit version (if used)	6.2.4

The line containing assignment of a boolean value to the array element is reported as not covered, however the rest of the assignments in the same array are reported as covered. The file coverage is reported correctly as 100% which probably means that this line is considered non-executable.

It looks like an Xdebug issue (#1479).
