424163 - topcrash [@ sqlite3BitvecSet]

Status: VERIFIED FIXED

(Core :: SQLite and Embedded Database Bindings, defect, P1)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

A new topcrash appeared in 2008-03-20 builds at the signature sqlite3BitvecSet.  Given that those builds have only been out a few hours so far, it's probably the #1 topcrash on trunk at this point by a good bit.

It's showing up on Windows and Mac.

Comment 1

[Ed Lee :Mardak]

Is this the same as bug 423943?

Comment 2

[Shawn Wilsher :sdwilsh]

I would suspect either bug 415947 or bug 423790 myself.

possible as well

Comment 3

[Dave Camp (:dcamp)]

423790 didn't touch any of the database access (or C++), I'd suspect 415947.

We may want to back-out Bug 415947 for beta 5.

Comment 6

[Mike Beltzner [:beltzner, not reading bugmail]]

Please do that, then resolve this bug.

Comment 7

[Shawn Wilsher :sdwilsh]

I won't have time to watch the tree to do that anytime before bake time is over - sorry.  Peter, could you handle that please (and re-open bug 415947 to pickup 3.5.8).

Comment 8

[Mike Beltzner [:beltzner, not reading bugmail]]

Peter, please see comment 5 and comment 7.

Comment 9

[Peter Weilbacher]

Seems like Gavin did the the backout before I had time to react, thanks!

No crashes anymore for 3 days. I think we can mark it verified.
