parted does not allow real overlapping partition with constraint mechanism.
Everytime overlapping happens, parted will try to find free space to
allocate for new partition.If no free space found, it will complain
with this exception and exit.
Then for security, when no proper allocation found, it should jump to error.
And an exception will be presented.
This also correct the bug for DASD for the situation below:
root@s35lp11:˜/workspace/TOOL_PARTED# parted /dev/dasde
GNU Parted UNKNOWN
