Re: problem with root 5.18

Hi Christian,

                I sent the mail to Debian Science because I think the problem isn't root one, but about my 64Bit Debian Os.
In fact the program name.C run without problem on another 32Bit Debian system (my desktop home).
In my opinion there is a problem with libc6 in my distro.

if you write on shell

dpkg -S /lib/libthread_db.so.1

dpkg return the package libc6.

What version of libc6 do you use with root 5.17?? I use this one 2.7-9.

Cheers,
Antonio
