This is a similar report as to http://bugs.xdebug.org/view.php?id=376

Sample code:

<?php

class Test {
function __construct($abc) {
$test = 'asdf' . $abc . "\n";
echo $abc;
}

function callTarget($arg) {
    $msg = 'Calling ' . $arg . "\n";
    echo $msg;

}
}

function outer($arg1, $arg2) {
$local = $arg1 . " " . $arg2 . "\n";
echo $local;
}

$t = new Test('someone');
$t->callTarget('12345');
outer("Time", "flies");

?>

If I place a breakpoint at any of the above "echo" lines, all local variables and function arguments are reported as uninitialized.

Note: This seems specific to Linux (or it may be I'm doing something wrong with the compiling of xdebug), as the prebuilt xdebug Windows binaries do not have this problem. I've tried both x86 and x86_64 Linux platforms - both experience the same problem.

The xdebug request/response is as follows:

context_get -c 0 -d 0 -i 39

<?xml version="1.0" encoding="iso-8859-1"?>
<response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="context_get" transaction_id="39" context="0">
<property name="abc" fullname="$abc" type="uninitialized"></property>
<property name="test" fullname="$test" type="uninitialized"></property>
<property name="$this" fullname="$this" address="14441248" type="object" children="0" classname="Test" numchildren="0"></property>
</response>

The initial xdebug handshake does confirm that I'm am indeed using the 2.0.5 version:

<?xml version="1.0" encoding="iso-8859-1"?>
<init xmlns="urn:debugger_protocol_v1" xmlns:xdebug="http://xdebug.org/dbgp/xdebug" fileuri="file:///home/toddw/tmp/p.php" language="PHP" protocol_version="1.0" appid="20417" session="Z3KUwFTDxTo=" idekey="toddw">
<engine version="2.0.5">
