Description:
When trying to index a large codebase (LLVM, clang and compiler-rt) Eclipse-CDT runs out of memory and the application appears to hang, after a while the program does become responsive again but I gave up trying to let it index.

I ran as

$ eclipse -consolelog -debug 2>&1 | tee eclipse.log

to gather debug output. I have truncated the log (original ~91MB in size) because it was huge.

Additional info:
* Eclipse 4.3.1-1
* Eclipse CDT 8.2.1-1
* gcc 4.8.2
* Truncated log output is attached.

Steps to reproduce:
1. Obtain source code

cd /some/folder
wget http://llvm.org/releases/3.3/llvm-3.3.src.tar.gz
tar -xvf llvm-3.3.src.tar.gz
cd llvm-3.3.src/tools
wget http://llvm.org/releases/3.3/cfe-3.3.src.tar.gz
tar -xvf cfe-3.3.src.tar.gz
mv cfe-3.3.src clang
cd ../projects
wget http://llvm.org/releases/3.3/compiler-rt-3.3.src.tar.gz
tar -xvf compiler-rt-3.3.src.tar.gz
mv compiler-rt-3.3.src compiler-rt

2. Run Eclipse
3. File > New > Makefile project with existing code. Point Eclipse to the /some/folder/llvm-3.3src folder
3. Select toolchain as "GNU Autotools chain"
4. Let Eclipse try to index the source code
