Fixed in 3.2.2
> mnogosearch v3.2.1
> i think i've found where is the problem in the code (sql.c) :

> (gdb) next
> 2879 Server.tag
>=strdup(UDM_EMPTY2NULL(UdmSQLValue(res,i,3)));
> (gdb) next
>
> Program received signal SIGSEGV, Segmentation fault.
> 0x400a39fd in __strdup (s=0x0) at strdup.c:42
> 42 strdup.c: No such file or directory.

> well, the same would be with category and charset if they are empty in the table..
> why do you use UDM_EMPTY2NULL ? cant strdup work with NULL argument

> then, I've set tag,category and charset to some nonempty value in my table.
> but there is still a segfault..

> below is something from gdb, note plz:
> 1.basic_auth is empty in my table, why do program step lines 2885-2891?
> 2. well, there is a call of UdmSQLValue in line 2893, but why it steps
> twise thru this func? (the same in previous calls of func - lines 2877..and then)
> 3.well, proxy is empty also, and the same thing - segfault
> (now, unlike tag,charset or category i cant set some stupid value for proxy -
>there is NO proxy)
