Bug#410131: libc6: running "mount / -o remount" gives glibc double-free

[Russell Coker <russell@coker.com.au>]

Package: libc6
Version: 2.3.6.ds1-10
Severity: normal

I had a system that (for unknown reasons) got a 0 byte mtab file.  When
running "mount / -o remount" to fix this I got a glibc error.  The mount
version is 2.12r-16.  This is repeatable in the latest etch with the
following commands:
# echo -n > /etc/mtab
# mount / -o remount
*** glibc detected *** double free or corruption (!prev): 0x0805d7d0 ***
Aborted
