Pranith, could you or someone with EC expertise help us diagnose this problem? 

The test script does: 

TEST touch /mnt/glusterfs/0/file{1..100}; 

I see some number of errors such as:

[2016-01-12 20:14:26.888412] E [MSGID: 122063] [ec-common.c:943:ec_prepare_update_cbk] 0-patchy-disperse-0: Unable to get size xattr [No such file or directory]
[2016-01-12 20:14:26.888493] E [MSGID: 109031] [dht-linkfile.c:301:dht_linkfile_setattr_cbk] 0-patchy-tier-dht: Failed to set attr uid/gid on /file28 :<gfid:00000000-0000-0000-
0000-000000000000>  [No such file or directory]

.. right before the crash. The backtrace is in mnt-glusterfs-0.log, it failed in ec function ec_manager_setattr(). 

It appears to be an assert, if I found the code right.

                    GF_ASSERT(ec_get_inode_size(fop,                                   
                                                fop->locks[0].lock->loc.inode,         
                                                &cbk->iatt[0].ia_size));
