Public bug reported:
Hi,
when I try to use apt-get (or similar) I found a Segmentation Fault:
apt-get dist-upgrade
Segmentation faulta dei pacchetti in corso... 0%
I tried to debug this with gdb, and:
-------
(gdb) run dist-upgrade
Starting program: /usr/bin/apt-get dist-upgrade
(no debugging symbols found)
(no debugging symbols found)

------
It seems the problem is in strlen. So I tryed this simple source:
#include <strings.h>
#include <stdio.h>
int main(int argc, char **argv)
{
if(argc>1)
printf("%d",strlen(argv[2]));
return 0;
}
and:
./a.out a
Segmentation fault (core dumped)
I've core files and other details if they'll be necessary.
Thanks...
