###!!! ASSERTION: 2nd pass should never guess wrong: 'pass == 0', file /builds/slave/m-cen-osx64-dbg/build/layout/generic/TextOverflow.cpp, line 540

Might be a regression from bug 690187.

the try server run
 will not execute the test 
"try: -b do -p all -u reftest -t none"

We should guess 'false' for a side that is inactive.
(the rendering should be correct so there's no need to fix this on Aurora)

I'm not able to reproduce the problem. Jesse, is there any chance to remember on what FF did you catch this?
Comment 9 User image Jesse Ruderman 2012-04-04 02:13:44 PDT
I think it was just a matter of loading the testcase in a debug build of Firefox.

I was able to see the crash on 2011-12-26-mozilla-central-debug build.
Verified fixed on FF 12 2012-04-04-mozilla-beta-debug on Win 7/64, Ubuntu 11.10 and Mac OS X 10.6.
