Summary REGRESSION(r27344): Crash on load at finance.yahoo.com
Mark Rowe (bdash)
Reported 2007-11-01 10:14:48 PDT
Steps to reproduce: 1. Load http://finance.yahoo.com/ 2. There is no step 2. Results: I have seen three different results: an assertion failure, a crash, and a unrecoverable hang. I'll attach the backtrace of the assertion failure as that is by far the most common symptom.
