Vassil Vassilev 009338beb7 Since cling::Transaction is public and the fact that on commit of transaction a 
new transaction could be triggered, every compile should return the transaction
that it actually compiled. I.e. the cling::IncrementalParser::getLastTransaction
in many cases might not be the transaction we expect. For example in ROOT's case
plugin manager is triggered for some reason and the last transaction is not the
one that I'd personally expect.
This should be fix roottest/.../runMemory.C

1.1 Dependencies

   CLING source depends on the LLVM [1] and CLANG [2] headers and libraries.
You will also need CMake [3] >= 2.6.1 or GNU Make to build all of those
packages and subversion [4] to get the source code.

   [1] http://llvm.org
   [2] http://clang.llvm.org
   [3] http://cmake.org
   [4] http://subversion.tigris.org/

1.2 Building

   To build LLVM and CLANG you must:

   * Check out the sources:

     mkdir src
     cd src
     svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
     cd llvm/tools
     svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
     svn co http://root.cern.ch/svn/root/trunk/interpreter/cling cling
     cd ..

   * Apply some patches

     cat tools/cling/patches/* | patch -p0

   * Configure, build and install them, either using CMake:

     cd ..
     mkdir build
     cd build
     cmake -DCMAKE_INSTALL_PREFIX=/some/install/dir \
           -DLLVM_TARGETS_TO_BUILD=CBackend\;CppBackend\;X86 \
           -DCMAKE_BUILD_TYPE=Debug \
           -DCMAKE_CXX_COMPILER=`which c++` \
           -DCMAKE_C_COMPILER=`which gcc` \
           ../llvm
     make
     make install

     or GNU Make (see ../src/configure --help for all options):

     cd ..
     mkdir build
     cd build
     ../llvm/configure --prefix=/some/install/dir
     make
     make install

2. U S A G E

   To interpret a C file type: "./cling test.c". To invoke cling in the
interactive mode type "cling" without file name.  Use ".L filename" to 
load libraries or C++ files.  Type C++ code at the prompt to interpret it.
