[Takis van Hoorn]

Hello i would like to report a bug regarding (g)parted,
specifically the "partprobe" function.

The version used was: 2.3.


//


Reporting the required output from the error as requested:

Assertion (head_size <= 63) at ../../../libparted/labels/dos.c:662 in function probe_partition_for_geom() failed.


//


The command execution and resulting backtrace:

address@hidden:/mnt$ sudo partprobe

A bug has been detected in GNU Parted.  Refer to the web site of parted http://www.gnu.org/software/parted/parted.html for more information of what could be useful for bug submitting!  Please email a bug report to address@hidden containing at least the version (2.3) and the following message:  Assertion (head_size <= 63) at ../../../libparted/labels/dos.c:662 in function probe_partition_for_geom() failed.
address@hidden:/mnt$

Additional info:

The bug occurs when launching partprobe while there is a usb device  connected from a certain manufacturer. Same bug doesn't occur with other
more or less similar devices. Tried three devices to rule out device errors:
 
Mediocre priced: "Verbatim 4GB"
el-cheapo priced device: "Brandless 4GB."
Overprized: "Kingston 4GB."

The Kingston device consequently caused the bug without any way to avoid it.


//


Can the bug be replicated?
Yes.

Required for replication: Usb 2.0 -stick / -device.
Brand: Kingston
Type: Datatraveller 100 G2
Capacity: 4GB

Step 1: plug in the usb -stick / -device.
Step 2: run partprobe


//

End bug info.

If required, please contact me for additional information.
I will be more then happy to help any way i can.


With regards,

T. van Hoorn.
