[Gluster-devel] GlusterFS 1.3.9tla786 unify client crashes while moving dirs

[NovA]

Hello everybody!

Since 1.3.9tla784 glusterFS crashes while moving dirs. For example,
the command "mv dir1/ dir2/" leads to crash with the following
back-trace:
-------
Program terminated with signal 11, Segmentation fault.
#0  unify_rename_cbk (frame=0x2aaab0ce8cd0, cookie=0x2aaab0ce9e20,

3266              for (index = 0; list[index] != -1; index++)

(gdb) bt

Also glusterFS unify crashes if it founds a duplicate of a file
(generated by previous glusterFS versions). In such a case the client
log ends up with lines:

Hope this can be fixed soon. :)
