827168 - "ASSERTION: reflow dirty lines failed: 'NS_SUCCEEDED(rv)'" with button, :first-line, flex

Status: RESOLVED DUPLICATE of bug 812822

(Core :: Layout, defect)

Description

[Daniel Holbert [:dholbert]]

(discovered this while tweaking the testcase on bug 824297)

The attached testcase (w/ :first-line and display:flex on a <button>) triggers this in a debug build:

###!!! ASSERTION: reflow dirty lines failed: 'NS_SUCCEEDED(rv)', file layout/generic/nsBlockFrame.cpp, line 1044

If I remove "display:flex", the testcase loads w/out any assertion-failures.

This might end up being the same as bug 824297, but the assertion-failure & style is different, so I figured I'd initially file it separately.

This is probably hitting the same issue described in bug 824297 comment 3.

(oops, just realized I forgot to attach the testcase. here it is.)

Comment 3

Verified that this testcase's assertion is fixed in trunk now, now that bug 812822 has landed.

Marking as dupe of bug 812822, and marking in-testsuite+ because this bug's testcase was included in that bug's crashtests push.
