[Gluster-devel] GlusterFS core dump (v1.2.3)

[Anand Avati]

Can you confirm that this still happens with a tla checkout from '
glusterfs--mainline--2.4' ? we have tested vim to be working. which version
of vi have you tried with? also is there a confirmed pattern in the file
permission/ownership which is causing this? since the coredump seems to be
in unify_getxattr_cbk, can you also check if the file has any extended
attributes from the backend fs?

thanks!
