--- Comment #12 from Brady Eidson <beidson at apple.com> ---
A few things I can see:

WK1-mac is, apparently, working great.

Release builds sometimes fail with text differences, but never crash
Debug builds "crash" - They're all asserts.

Example assert:

No crash log found for com.apple.WebKit.Databases.Development:81065.

stdout:

stderr:
ASSERTION FAILED: !m_db.m_transactionInProgress

-Windows WK1 debug is seeing the crashes too, but I can't get windows crash logs.
