I've selected 'Product Version' 2.2.6 (PHP 5.x) but it also occurs while using the current 2.4 master you had me download for use with PHP 7.0 so I do not think the issue is related to a specific version of Xdebug.

I do not know if this issue is one with Xdebug or Eclipse (Neon)/PDT (3.7) - I welcome your thoughts.

I've attached a log. In it you can see a breakpoint is set on line 6 of the code listed below (line 30 of the log file). You can see the breakpoint being removed on line 48 of the log file. However, the Xdebug response is code 205. Is it that the command issued by Eclipse is wrong or is the Xdebug response incorrect?

I see the same behaviour when using Eclipse (Luna)/PDT (3.6).

<?php
ini_set( 'display_errors', true );
$a = true;
while ( $a )
{
$ver = phpversion();
}
return;
