Build Identifier: CDT: 20100917-0705 & Platform Build id: M20100909-0800

This error comes & goes, and was gone all morning.  Then I started writing a new method, and it's popping up after each modification + save of the file.  A dialog pops up saying "'Notifying selection listeners' has encountered a problem.  An internal error occurred during: "Notifying selection listeners".  The details show only java.lang.StackOverflowError.  Log suggested that maybe the DOM got built incorrectly, and then the indexer for templates freaks out.  NOTE: I've rebuilt the entire index multiple times, hoping it would fix this problem, but it does not.

Reproducible: Always

Steps to Reproduce:
1. Write some non-templated method, save file.
2. Error pops up.
3.

log, showing nothing more than endless StackOverflowErrors from this issue.

Uploading logs, which don't shed much light onto why this is occurring.  It's pretty easily reproduceable for me, so get in touch if there's a way to increase logging, or if I can export DOM or indexer files, etc.

Thx,
Mike

different log, from different workspace

Attaching a different log of a similar occurrence, from a different workspace.  I can get this error to pop up any time I select a particular method name.

Bumping importance.  This bug is now affecting all of my workspaces for a given source tree, and the only way around getting the pop-ups every 5 seconds is to turn off the indexer.

Can I help debug this?  Easily reproduceable here.

Thx,
Mike

improved safeguard against the recursion

I am interested in debugging the issue. For that I need a way to reproduce it. Do you have a piece of code that you can give away (eiter via bugzilla or via direct email to me), which also triggers the bug?

We already have some safeguard in place that should have caught the recursion, I have improved it.

Improved safeguard in 8.0 > 20101104.
Please verify that it actually helps with your code-base.

Hi Mark,
Thanks for the interest in this one.  I don't have a small project that can reproduce this.  I can't figure out which typedef is causing heartburn for the Indexer.  Could CDT possibly log the offending typedef which causes this recursion?

I'll download your fix in a build greater than 20101104.  Is it safe to have 2 different versions of the CDT plugin installed in the same Eclipse platform?

Thx,
Mike
