Description Yan Ma CLA 2010-10-05 20:05:46 EDT 
Build Identifier:  I20100603-1500

An x10 process will hang somewhere forever after a global BP is set and disabled.

Reproducible: Always

Steps to Reproduce:
source file:ArraySum.x10 
executable:ArraySum.out  compiled by X10C++ 
Reproducibility: yes

Step 1: Set a global BP at line 50.
Step 2: select the BP and right-click your mouse. Choose "disable breakpoint".
Step 3: Make sure the icon for global BP becomes blur, which indicates the BP has been disabled.
Step 4: Start running the above X10 program. 
Step 5: When the cursor stops at the entry of main function, click "Resume" in debug view.

Result: The process could hang forever (I tested three times and no resumption happened after at least 10 minutes waiting for any of three experiments).

This can be reproduced on a simple test case.
