Heiko,

You are right. I did not check carefully the cause. Now I'm wiser, because I 
read the sources.

Before I wrote first mail, I checked the same with these new versions of samba 
and cifs-utils. It did not solve the problem. Anyway, thanks for the upgrade.

The problem is with realpath function, which is used in mount.cifs to 
canonicalize mount point path. Two specifications are used for this function: 
one assumes that the second argument is obvious pointer to the buffer for 
canonicalized path, and the second allows to NULL pointer, when realpath 
should malloc memory for that buffer. mount.cifs uses second form and gives 
NULL pointer to this call, but for some reason (for me at least), realpath is 
not accepting NULL in the second parameter and gives error. Well, only in 
32-bit compilation. Maybe because of some additional packages, added myself, 
cifs-utils catch invalid library? I have to find the cause or patch cifs-utils.
