507495 - Crash [@ UnhookTextRunFromFrames] on print preview with floats, page-break, ::first-line, etc

Status: RESOLVED WORKSFORME

(Core :: Layout: Floats, defect)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, which crashes current trunk build on print preview, sometimes.

This seems to have regressed between 2009-07-13 and 2009-07-15:

I think a regression from bug 499377.

The testcase contains some code that automatically opens a new window and sets it in print preview, periodically, to make it easier to reproduce the crash. You need to grant enhanced privileges to let it work.

Could not reproduce on Windows or Linux using recent trunk.

Yes, seems to have become worksforme.
