Description:
------------
This bug only occurs for some image resources.

In the following example php fails with error "Segmentation fault":

Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x0000559dbe907bcf in _php_stream_seek ()

Apperatently this is only caused by ImageMagick::writeImageFile(fopen('php://temp', 'w+'))

ImageMagick::writeImageFile(fopen('/tmp/image.jpg', 'w+')) and ImageMagick::writeImage('/tmp/image.jpg') works fine.

I've attached the failing TIFF image as a patch file.

Test script:
---------------
$imagick = new Imagick('/tmp/89538763640163');

$imagick->setInterlaceScheme(Imagick::INTERLACE_PLANE);
$imagick->stripImage();
$imagick->thumbnailImage(140, 200, true, true);

$handle = fopen('php://temp', 'w+');

$written = $imagick->writeImageFile($handle);

That Website is no longer available; could you please make that
file available for download again (assuming the issue still exists
with the latest imagick 3.5.1)?
