Tiff image leading to segfault and core file are here: http://depositfiles.com/ru/files/1353jtvg1 (sorry for ads, but don't see how to attach files here)

Note: GIMP also fails to load the image complaining it contains some outdated features.
The image was produced by one of microsoft products.

I have no problem with that file - with IM v6.6.4-8 Q16 (on Windows). So, my advice would be to update ImageMagick. There were a few patches for such TIFF files lately. It could also depend on the libtiff version on your system (with the Windows distributions, libtiff v3.9.2 is used).

result is the same. Libtiff is 3.9.4

Code: Select all

$ ldd /opt/imm/bin/convert|grep tif
	libtiff.so.3 => /usr/lib/libtiff.so.3 (0x00007f024d071000)
$ ls -l /usr/lib/libtiff.so.3
lrwxrwxrwx 1 root root 16 Jun 28 00:24 /usr/lib/libtiff.so.3 -> libtiff.so.3.9.4
Debugger shows that it really fails somewhere in libtiff. I had to check it first.

OK, seems that the latest IM patches didn't change these general problems. (You're not the only one with such errors - see e.g. here.) It really seems to be a libtiff issue.
I guess libtiff has to be compiled with special switches so that it can still read the 'Old JPEG' in TIFF compression. Can't give you more specific hints - I'm just a Windows user and don't have these problems. (The Windows IM/libtiff distribution can read most of these files right from the start.)

I've tried to recompile libtiff without --disable-old-jpeg flag, but got no effect.

It looks like the problem is not 'old jpeg' stuff, but a bug somewhere in a library - maybe it's 64 bits-related. Since gimp (using same libtiff) can complain about unsupported 'old jpeg' stuff this means library is robust enough to report some incompatibility. But segfault is not an expected behaviour.

Below is backtrace if you are interesetd. I guess this bug should be reported against libtiff.
