(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.
Summary: first-line flex → "ASSERTION: reflow dirty lines failed: 'NS_SUCCEEDED(rv)'" with button, :first-line, flex
This is probably hitting the same issue described in bug 824297 comment 3.
Created attachment 700011 [details] testcase 1 (oops, just realized I forgot to attach the testcase. here it is.)
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.
