1. When I open the latest sources for gcc suite (not building with gcc but opening the project with gcc sources tree), the indexer seems to hang on 3% of the project, on call2.C. See the screenshot.

2. Additionally, there is a number of reports by Error Log view. I don't report them in detail since you could see that yourself. These are:

Additionally, when 'Close project' is selected on a gcc sources project, it hangs (see screenshot2). When the eclipse app is closed, it waits for these tasks to finish, and the only way to close the eclipse is killall eclipse.

gcc 4.6.0 test suite still hangs with cdt-master-7.0.2-I201012200303.zip available at https://hudson.eclipse.org/hudson/job/cdt-release/lastSuccessfulBuild/artifact/all/org.eclipse.cdt.releng/results/I.I201012200303/cdt-master-7.0.2-I201012200303.zip .

gcc 4.6.0 was taken at:
URL: svn://gcc.gnu.org/svn/gcc/trunk
Repository Root: svn://gcc.gnu.org/svn/gcc
Revision: 167217
Revision Date: 2010-11-28

I installed a fresh eclipse-java-helios-SR1-linux-gtk.tar.gz and the above cdt7.0.2 into it. The C/C++ indexer hung on equal.cc:
gcc460/libstdc++-v3/testsuite/26_numerics/random/discard_block_engine/operators/equal.cc .

Additionally, Error Log shows a stack overflow exception:

OK. I would suggest closing this bug and filing a new one if you encounter a StackOverflowError (or other exception) again.
