Hello,

As a part of a system I am working on, tiffinfo is used to figure out if files seen as tiff images by ImageMagick are actually tiff or raw. We have a test suite that shows that this works just fine on RHEL4 with libtiff 3.7.1 installed but when running these tests on RHEL5, which has the latest stable version of libtiff, one of the test cases fail. I was able to find that tiffinfo seg faults which does not allow our code to get the info it needs from tiffinfo.

Here is the output:

$ tiffinfo RAW_LEICA_M8.DNG

Segmentation fault

Not knowing if this was a libtiff issue or RHEL5 issue I installed it on my Mac OS X 10.5.5 system using macports and I got the same result except that "Segmentation fault" read as "Bus error".

Any thoughts? I can make the 10 MB file available upon request.

Thanks,
