I'm having trouble reproducing it - can you tell me the exact git clones and composer installs that I need to run?

Hi, Derick - thanks for responding!

As far as the XDebug versions/branch, I have been able to reproduce this issue with 2.3.0, 2.3.1, and the xdebug_2_3 branch which the screenshot in the original report showed as "v2.3.2-dev".

To replicate using the code, perform the following:

1. Clone my fork:
   $> git clone git@github.com:jimdelois/php-code-coverage.git

2. Switch to the branch that just has the one-line change which adds the XDEBUG_CC_BRANCH_CHECK to xdebug_start_code_coverage within src/CodeCoverage/Driver/Xdebug.php
   $> cd php-code-coverage/
   $> git fetch
   $> git checkout feature-path-coverage

3. Initialize the project
   $> composer install

4. Run the test suite for this project, which reproduces the error.
   $> ./vendor/bin/phpunit

I have reproduced this error on PHP 5.6.5 (Mac/homebrew), and Ubuntu PHP 5.6.4 (Docker)

I can reproduce this now too. A fix will have to wait a little while as I'm out of country for a few days.

Great! I'm thrilled to hear that you can reproduce the issue.

The community is very excited about this feature, as I'm sure you're aware. Please don't hesitate to let me know how I can assist.

Thanks again!

Fixed - I think.
