Package: xfsprogs
Version: 3.2.1
Severity: important
xfs_growfs did corrupt a filesystem on a up2date Debian Jessie system.
Might be a kernel problem and not xfsprogs related.

Some more info
The system in question is a virtual machine (KVM), the host being
Debian Jessie, too.
The VM had a 100G xfs filesystem mounted on /home with only appr. 450MB
free disk space and was shut down to do the resizing of the underlying
"physical disk" (/dev/vg_HOST/vm_1 on the Host).
The VM was shut down and after that lvresize was used on the HOST
to resize the VMs assigned block device.
The VMs "disk" changed from 100G to 150G and the partitions changed from
------snip------
Disk /dev/vg_HOST/vm_1: 150 GiB, 161061273600 bytes, 314572800 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

The VM was then started.
Inside the VM the above mentioned commands were issued.
Just for reference: the hosts logical volume is assigned to the VM
in question in the following manner (using libvirt syntax):
<disk type='block' device='disk'>
<driver cache='none' io='native'/>
<source dev='/dev/vg_HOST/vm_1'/>
<target dev='vda' bus='virtio'/>
</disk>
