408744 - "ASSERTION: bad height: 'Not Reached'" with -moz-column and very tall div

Status: RESOLVED WORKSFORME

(Core :: Layout, defect)

Description

[Daniel Holbert [:dholbert]]

I'm seeing lots of copies of this assertion:

###!!! ASSERTION: bad height: 'Not Reached', file /mozilla/layout/generic/nsLineLayout.cpp, line 185

when I load the testcase.

NOTE: The "wrapper" div's height doesn't matter, as long as it has *some* specified height.  I'm only giving it a large height so as not to trigger the hang from bug 408737.

NOTE: Removing the -moz-column style and/or removing the specified height on "wrapper" will prevent the assertion from firing.  We do still get lots of debugging
   nsBlockReflowContext: Block(div)(1)@0x884ef30 metrics=62760,24562499!
type messages, but those are expected I think.
