Hi Andy,

Here's the build error I told you before (see patch of 
src/XrdSsi/XrdSsiSfsConfig.cc):
--------------
[ 90%] [ 91%] Building CXX object 
src/CMakeFiles/cmsd.dir/XrdCms/XrdCmsAdmin.cc.o
/home/qserv/src/xrootd/src/XrdSsi/XrdSsiSfsConfig.cc: In member function 
'bool XrdSsiSfsConfig::Configure(XrdOucEnv*)':
/home/qserv/src/xrootd/src/XrdSsi/XrdSsiSfsConfig.cc:234:16: error:

[-Werror=maybe-uninitialized]
     if (!myArgv || myArgc < 1)
                ^
Building CXX object 
src/CMakeFiles/XrdFileCache-4.dir/XrdFileCache/XrdFileCacheFactory.cc.o
--------------

The build error occur with next cmake command:
--------------
cmake /home/qserv/src/xrootd 
-DCMAKE_INSTALL_PREFIX=/home/qserv/src/xrootd/_eupspkg/binary/xrootd/qservSsi-g152d04bad9-dirty 
-DENABLE_PERL=FALSE
--------------

Please note that this error doesn't occur using next cmake command 
(debug mode):
--------------
cmake /home/qserv/src/xrootd -DCMAKE_BUILD_TYPE=Debug 
-DCMAKE_INSTALL_PREFIX=/home/qserv/src/xrootd/_eupspkg/binary/xrootd/qservSsi-g152d04bad9-dirty
--------------

As a reminder, here's a (trivial) patch proposal:

--------------------------

diff --git a/src/XrdSsi/XrdSsiSfsConfig.cc b/src/XrdSsi/XrdSsiSfsConfig.cc
