Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Run chrome with gcc front-end.
2. Wait for long enough.

What is the expected output?
The program continues to run.

What do you see instead?
The program crashes.

Here is the stack:

Program terminated with signal 6, Aborted.
