piece of source code that triggers the bug? I am getting those coming to the log but haven't figured what causes it yet. Any pointers which user action could trigger that? Is it hovering, F3, opening a file, editing? (In reply to comment #4) > I am getting those coming to the log but haven't figured what causes it yet. > Any pointers which user action could trigger that? Is it hovering, F3, opening > a file, editing? The reconciler is called to build the CModel for the currently open source file. It gets triggered when you open the file, and also when you make edits (after a short delay of non-activity on the user's part). I got something different, maybe a different bug though:

Then after editing some more, I noticed that semantic highlighting was not working at all anymore. Looking at the threads:
- 3 CReconciler threads waiting in AbstractReconciler:179 fDirtyRegionQueue.wait(fDelay);
- 1 CReconciler in an infinite loop in org.eclipse.cdt.core.parser.util.HashTable.linkIntoHashTable(int, int)
while (nextTable[j] != 0) {
// if (nextTable[j] - 1 == j) {
// break;
// }
j = nextTable[j] - 1;
}
value of nextTable[0] was 1
I was editing OgreMesh.cpp (http://www.ogre3d.org/)
(In reply to comment #6) Most likely this exception is the result of concurrently accessing the same AST from different threads (The code of the HashTable has not been changed in the last 3 years). (In reply to comment #7) > (In reply to comment #6) > Most likely this exception is the result of concurrently accessing the same AST > from different threads (The code of the HashTable has not been changed in the > last 3 years). It certainly looks this way. I have troubles to corner the exception, it always slips behind the radar. The closest I happen to notice was that I was doing a search on a macro (#define) then checking the occurrences. Then I manually renamed the macro, navigated to search results and fixed all the occurrences. When my attention released from rename process the exception was there. I don't really know what exactly action triggered it. *** Bug 344440 has been marked as a duplicate of this bug. *** (In reply to bug 344440 comment #5) > (In reply to comment #4) > > The same infinite loop is reported in bug 343175 comment 6 > > *** This bug has been marked as a duplicate of bug 343175 *** > Confirmed.
