[Crash-utility] [ANNOUNCE] crash version 7.2.2 is available

[Alex Sidorenko]

Well, stepping in GDB line-by-line I can see that we segfault at #1594 in filesys.c

1588            if (!one_vfsmount)
(gdb)
1589                    FREEBUF(mntlist);
(gdb)
1590            if (VALID_STRUCT(mount))
(gdb)
1593                    FREEBUF(vfsmount_buf);
(gdb)
1594 FREEBUF(super_block_buf);
(gdb)
1595    }
(gdb)
0x0000000000000000 in ?? ()

That is, there is definitely memory corruption somewhere and 'mount' is most probably just a victim.
