When I enable both the GD & DB extensions, then make a call to a GD function I get a visit for Dr. Watson.

Please give more info. Are you using CGI binary?
Or ISAPI module? With which web server?

AFAIK. GD is not thread safe yet.

User feedback:
-----------
The described Problem (can't confirm that it's connected to
DB-extensions, but I have mssql_70 active), occurs
only in CGI-mode using IIS as Web-Server.

In ISAPI-Mode, Dr. Watson doesn't come up. Instead, the following
warnings occur, but the resized files get
saved properly (but you can prevent occuring this warnings with
@imagedestroy( $im ), so I think it's somehow
connected to the "shutdown process" [Don't know your semantics, but I
hope you know what I mean ;-) :

Warning: Unknown list entry type in request shutdown (1042368) in Unknown on line 0
Warning: Unknown list entry type in request shutdown (1042368) in Unknown on line 0

Under ISAPI, I've got this warnings since PHP 4.02  (see also Bug id #6539).

Here is a small testfile (for copy-paste-run), where Dr. Watson (cgi) or
the above warings (isapi) come up:

<?
if (!isset($DOCUMENT_ROOT))       // Only for CGI-mode
 $DOCUMENT_ROOT = "F:\\Inetpub\\www\\Intranet";

$mypath = $DOCUMENT_ROOT."\\misc\\punsch\\photos\\";

if ( $op == "save" && $userfile_name !="" ) {
 $imgtype = substr ($userfile_name, strlen($userfile_name)-3, 3);

 if ( copy($userfile, $mypath.$userfile_name)==1 ) {
  $imgsize = getimagesize ($mypath.$userfile_name);
  $im_w = round( $imgsize[0] / ($imgsize[1]/45) );
  $im_h = round( $imgsize[1] / ($imgsize[1]/45) );
  $im = @ImageCreateFromJPEG ($mypath.$userfile_name);

  $im1 = @ImageCreate ($im_w, $im_h);
  imagecopyresized ( $im1, $im, 0, 0, 0, 0, $im_w, $im_h, $imgsize[0], $imgsize[1]);
  imagejpeg ( $im1, $mypath."tn_".$userfile_name );
 }
}

Could you try the latest build from 
http://www.php4win.de/ and try using DBA instead of DB ?

(BTW. there is a note in the FAQ that says you should only
use GCI version if you want to use GD extension..)

No feedback. Try PHP 4.0.4 and reopen if problem still exists.
