I am using Eclipse 4.7.1 on a WIndows 7 64-bit machine.

If I create a set of nested projects, i.e.:
   project A (file system location: $workspace/A}
     project B (file system location: $workspace/A/B}

When I delete project A, it also removes project B - but the indexer PDOM file for project B remains behind in $workspace/.metadata/.plugins/org.eclipse.cdt.core.

[Note: If I first delete project B above, and then project A, there are no indexer PDOM files left behind and I do not see the problem noted below.]

With PDOM files left behind, this causes the following problem:
Once I recreate the same set of nested folders as above, within the same Eclipse session,  the indexer will run, but will open an error dialog with many "C/C++ indexer error" messages in it. 

Note that I cannot delete the left-behind indexer PDOM files noted above until I close the current Eclipse session; the indexer appears to be locking them. Once I restart Eclipse however, I can recreate the folder hierarchy noted above without a problem - new indexer files are created at this point and all is well.
