index ignores my .cpp, no matter what [message #1386147]

I have set -Xms512m -Xmx2048m and the memory usage of java is 1G. The cache limit is set to the highest possible values (75%, 2G max). I have manually selected the folder that contains this file as a source folder, and all the other compilation units there are being parsed. This file here instead is big and somehow it hits an hard hidden limit, and whenever I try to, for example, get all the references to a variable (ctrl + alt + h), it says that the file is not currently in the index.

Quite unnerving.

In Preferences->C/C++->Indexer is a hard limit for files bigger than 8 MB. There are also the limits for the indexer cache defined. Perhaps you hit one of these.

And there is a scalability limit defined in Preferences->C/C++->Editor->Scalability. It will turn off indexing files that exceed a certain amount of lines. You should check this, too.

If all above fails...

Tracing the CDT indexer:
* use command line option -debug <options-file>
* put the following in the options file:

# turns on tracing for the cdt-core plugin
org.eclipse.cdt.core/debug=true

# Reports sequence of files indexed
org.eclipse.cdt.core/debug/indexer/activity=false

# Reports statistics for indexer
org.eclipse.cdt.core/debug/indexer/statistics=false

# Reports unresolved inclusions for indexer
org.eclipse.cdt.core/debug/indexer/problems/inclusion=false

# Reports scanner-problems for indexer (other than unresolved includes)
org.eclipse.cdt.core/debug/indexer/problems/scanner=false

# Reports syntax-problems for indexer
org.eclipse.cdt.core/debug/indexer/problems/syntax=false

# Reports problems for indexer, including inclusion-, scanner-, syntax- and
resolution-problems.
org.eclipse.cdt.core/debug/indexer/problems=false

What should I look for? The debug file is loaded, but nothing particular is printed on the console.

EDIT:
it actually prints twice "### Excluding compile: org.eclipse.cdt.internal.core.pdom.dom.cpp.PDOMCPPLinkage::addBinding", but not when I click on index->reubild
