What steps will reproduce the problem?

1.Just run with following command:
2./usr/local/bin/tesseract /dir/logo.gif.tif /dir/logo.gif

What is the expected output? What do you see instead?

Can you please provide testing image? I can try it in tesseract from svn.

I've attached the image, which is causing segfault.

I can not reproduce problem. I tried it on Windows XP SP3 and it was without 
problem. I tried it on Centos 5.7 (I do not have CentOS 6.2) with tesseract 
3.01 and 3.00 and it worked...
So it does not seem to be tesseract problem.

Did you build tesseract by yourself or did you installed it from some package?
Can you send 'ldd /usr/local/bin/tesseract'?

Yes, I compiled it.

Following is the output from ldd:

Just to confirm: have you installed the required language data files (which 
were updated for v3.01)?  I can reproduce this exact error (i.e., a SEGFAULT in 
ComputeIntCharNormArray) if the "XXX.traineddata" (and associated files) aren't 
present (or aren't readable in the expected location).  The language-specific 
training files are available from the downloads page.

Hi,

Thanks, works like a charm after installing the language pack.

Can you please tell me how can I install all the languages pack?

If you downloaded/used tesseract-3.01.tar.gz, than you have to download all 
relevant files manually and install them manually.

Or you can use svn version: install svn and than run:
$ svn checkout http://tesseract-ocr.googlecode.com/svn/trunk/ tesseract-ocr
$ cd tesseract-ocr

and follow instruction in INSTALL.svn[1] But be aware: language data files are 
more than 600MB!
