[Bug 1342255] Re: `malloc(): corrupted unsorted chunks 2` after copying data from hfsplus partition with cp

[Phillip Susi]

Right... the cross thread write was introduced by "Prevent GSource
double-destroy...".  The fix for that is now in my ppa and I will have
it merged into utopic soon.  The fix for the other bug I think applies
to both trusty and utopic so I will need to apply that as well.

Title:
  `malloc(): corrupted unsorted chunks 2` after copying data from
  hfsplus partition with cp

Status in “gparted” package in Ubuntu:
  Confirmed

Bug description:
  After copying data from a `hfsplus`to a `fat32`/`vfat` partition on an
  USB stick with `cp` of busybox 1.20.2 in a Lubuntu 13.04 live session
  on an `iMac G4 PowerMac 6,1`, gparted crashes with

    * `*** Error in `/usr/sbin/gpartedbin': malloc(): corrupted unsorted chunks 2: 0x0000000000b93e10 ***` if I request the `vfat` partition to be made smaller and an ext4 partition to be created on the freed space
    * `Attempt to write sectors 4026-4089 outside of partition on .
  *** Error in `/usr/sbin/gpartedbin': corrupted double-linked list: 0x0000000002303740 ***` if I request the `vfat` partition to be made smaller only

  The USB stick is a SanDisk Extreme USB 3.0 with 64 GB capacity. Two
  primary fat32 partitions (formatted with gparted) are present on a
  `msdos` partition table.

  Experienced with 0.18.0 on Ubuntu 14.04.
