Description of problem:
While running the glusterfs_build : git clone followed by autogen and configure.As soon as we run configure the smbd crashes and dumps core.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Create a volume .
2.Mount via cifs on Linux client
3.Do a git clone git://github.com/gluster/glusterfs.git glusterfs.git
4.cd glusterfs.git/
6 ./configure

The core will get generated and configure will throw following error:

Actual results:
The smbd crashes.

Expected results:
The glusterfs_build should run successfully.

Additional info:
Comment 2 Christopher R. Hertel 2013-09-03 20:16:50 EDT
Update:  The stack trace given above does not pass through the EA handling.  This is a crash under heavy load.

The load, in this case, is building Gluster itself.  The stack trace shows that the crash occurs in the Gluster layer.  SMBD crashes because it is linked to the Gluster client library.

Comment 5 surabhi 2013-09-06 07:22:32 EDT
Verified the bz with latest version

Executing following steps doesn't generates core and tests ran successfully.

1.Create a volume .
2.Mount via cifs on Linux client
3.Do a git clone git://github.com/gluster/glusterfs.git glusterfs.git
4.cd glusterfs.git/
6 ./configure

[root@RHEL6 stat-prefetch]# cd glusterfs.git/
