[support] preg_match failes where egrep and PERL succeed?

[Luke]

Hello

I do not wish to say how long I have been trying to figure this out.

I have a node with a CCK textarea, containing data like this:

123|aabbcc
456|10fe1c
...

In other words, a three digit reference to a hex code.

I am attempting to use a computed field to search that node for the 
reference (three digit code), and return only the hex value.

I am using a regular expression to do this.  I have tried several varients 
of the regexp, all of which work whether I use them in PERL or egrep.
However, when I use drush to test them with preg_match, the test fails 
every time.

What might I be doing wrong here?  This was supposed to be done hours 
ago, of course.

drush 2> /dev/null eval '$datanode = node_load(2736);
$res = preg_match('\''/^200\|([0-9a-fA-F]+)/'\'', 
$datanode->field_int_data[0][value], $match); echo $res . ": " . $match[1] 
. "\n";'

The output is:

0:

However:

drush 2> /dev/null eval '$datanode = node_load(2736);
echo $datanode->field_int_data[0][value];' | perl -e 'while (<>) { print 
$_ if (/^200\|([0-9a-zA-Z]+)/); }'

I get:

200|EEC57C

I gather that the PCRE library has changed some things, but I did not 
think the handling of subpatterns was one of them, so I am quite 
perplexed.  It's probably something quite simple.

N.B.
The reason I am redirecting STDERR to null, is because I get this warning 
when running drush.

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/lib/php5/20060613+lfs/imagick.so' - libWand.so.9: cannot open shared

with no apparent resolution.
