709000 - Segfault in sqlite3_db_status

Status: RESOLVED DUPLICATE of bug 708248

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

Description

[Jonathan Protzenko [:protz]]

Attachment: bt full

So I initially had the problem that my addon wasn't closing its sqlite connections properly, but I fixed that (I think), and now it shouldn't be a problem anymore.

Attached is a gdb bt after it happened. Please note that this didn't happen a week ago or so.

Also, here's what call DumpJSStack() gave

Note that I did fix the problem with my addons 6 months ago, and the crashes stopped at that time, and now the crashes in sqlite are back, which makes me think it's a different problem.

I think this is just a dupe of bug 708248.

Yes, it's a duplicate.  Thanks for reporting!
