safe mode and passthru

[Yemi]

Hi There.

I seem to be getting some inconsistent results when using passthru()
in safe mode. They appear to be related to the fact that passthru
should treat all command arguments as one single argument when safe
mode is on. Everything works just fine on my MacOS X webserver (
Apache 1.3.29 with PHP 4.3.6 ). But on my Linux Enterprise 3.0
production server (running Apache 2.0.46 with PHP 4.3.2) things are
different.

Here are the argument(s) that passthru hands to my command when safe
mode is off:

rrdtool args: graph - --start -3600 --end N --width 300 --height 75
--lower-limit 0 --rigid --title BaBarCM2 Grid Load last hour
--vertical-label Load/Procs
DEF:load_one=/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/load_one.rrd:su m:AVERAGE
DEF:proc_run=/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/proc_run.rrd:su m:AVERAGE
DEF:cpu_num=/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/cpu_num.rrd:sum :AVERAGE
DEF:num_nodes=/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/cpu_num.rrd:num :AVERAGE
AREA:load_one#C CCCCC:1-min Load LINE2:num_nodes #00FF00:Nodes
LINE2:cpu_num#F F0000:CPUs LINE2:proc_run# 0000FF:Running Processes

And this is what passthru hands to my command when safe mode is on:

rrdtool args: graph - --start -3600 --end N --width 300 --height 75
--lower-limit 0 --rigid --title 'BaBarCM2 Grid Load last hour'
--vertical-label 'Load/Procs'
DEF:'load_one'= '/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/load_one.rrd':' sum':AVERAGE
DEF:'proc_run'= '/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/proc_run.rrd':' sum':AVERAGE
DEF:'cpu_num'='/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/cpu_num.rrd':'s um':AVERAGE
DEF:'num_nodes' ='/u2/ganglia/rrds/BaBarCM2/__SummaryInfo__/cpu_num.rrd':'n um':AVERAGE
AREA:'load_one' #CCCCCC:'1-min Load' LINE2:'num_node s'#00FF00:'Node s'
LINE2:'cpu_num' #FF0000:'CPUs' LINE2:'proc_run '#0000FF:'Runni ng
Processes'

The quotes are still there. Why am I not getting consistent behaviour
on both platforms? Is this a bug in php 4.3.2 or 4.3.6???
