StackOverflowError while debugging a large PHP file (Drupal 7's common.inc, 7,000+ lines).  Prior to crash, 1 cpu at 100%.  Error message says task at fault is Semantic Highlighting.  With this hint, I discovered a work-around--uncheck the preference "General/Editors/Structured Text/Enable Semantic Highlighting".

Here's the log:
!ENTRY org.eclipse.core.jobs 4 2 2011-09-26 14:08:03.301
!MESSAGE An internal error occurred during: "Semantic Highlighting Job".

Reproducible: Always

Steps to Reproduce:
1. Create a project containing a clean install of Drupal 7
2. Set a break point in common.inc, or step into it
3. Performance is sluggish, then crashes with a message something like, "StackOverflowError in task 'Semantic Highlighting', do you want to close Eclipse?"
