Package: clamav
Version: 0.96.5+dfsg-1~volatile1
Severity: important


Clamscan crashes when scanning a windows file (nmap-4.10-setup.exe). 

The copied file has been on our server since 2006, but the problem
only occured recently with one of the last updates of clamav in debian lenny.

The error can be repeated.

Error message: Illegal instruction (core dumped)

I will provide the clamscan log, the clamscan debug log, a screenshot and the file nmap-4.10-setup.exe with a second 
email.

If really necessary and demanded, I will find a way to provide the coredump file core.9723, as it's size is 
uncompressesd 103M.

There has been an similar bug in October 2010 under the bug reporting number 600088. This problem has been solved by 
Toeroek Edwin and i have no way to find out if this new one might be a similar problem.

Debian is running on an old AMD K6-2 CPU here as a server for a small workgroup.
