Problem still exists using latest CVS snap and GD 2.0.4. (I thought I
would mention it 'cause I have seen lots of GD work being done in
both.)

Did test http://144.92.10.251/riverdata/images/uncompressed_med.gd2
and
got the following:
$ php 19817.php
Error from seek: 25

The interesting thing I think is "Error from seek: 25" which actually
comes from the bundled libgd from libgd/gd_gd2.c from
gdImageCreateFromGd2PartCtx, line 584:
if (gdSeek (in, dpos) != 0)
{
printf ("Error from seek: %d\n", errno);
goto fail2;
};
Error code 25 means "Inappropriate ioctl for device", no idea why this
happens though.
Maybe a problem related from mixing PHP Streams and native access to
FILE fd's ?

Will a backtrace work? PHP isn't crashing, just giving an
error.

I'm going to say.. it's probably not an OSX/Darwin issue. GD is GD,
and it's been proven to be buggy in the past. Although my hunting time
is limited, I'll try to look at it later tonight.
Can you by any chance include a backtrace for this?
