xfs_db crashes sometimes

[Bremm]

Binary package hint: xfsdump

Last night the command below worked fine. But now:

$ sudo xfs_db -c frag -r /dev/sda5
Falha de segmentação

[2046627.210827] xfs_db[16146]: segfault at 2125000 ip 0000000000434b80 sp 00007fff424ff0f8 error 4 in xfs_db[400000+71000]

Oddly, it didn't happen few hours ago. But happened few weeks ago... And I don't know which conditions trigger it.

Folks, it might be related to the free space in the partition. I'll keep testing to see what's the limit.
