stream segfaults while reading certain TIFFs

stream is segfaulting while reading certain multipage TIFF files. I was using it to pipe input to convert for reading very large files. If I convert them to vips (raw) and back to TIFF using raw2tiff (from libtiff), then stream reads them just fine. The file used to generate the debugging output below is about 10GB, but I'll provide a link to a smaller file (75MB) that I have confirmed causes segmentation faults as well.

We can reproduce the problem you posted and have a patch in ImageMagick 6.6.1-9 Beta available by sometime tomorrow. Thanks.
