1. Load testcase

Uses to load the target.svg then calls sizeToContent() on it.

ABORT: root should not have auto-height containing block: 'aCBSize.height != NS_AUTOHEIGHT', file /work/mozilla/builds/nightly/mozilla/layout/svg/base/src/nsSVGOuterSVGFrame.cpp, line 342

also on winxp.
Comment 3 Martijn Wargers [:mwargers] (not working for Mozilla) 2011-08-31 13:41:54 PDT
Is the testcase supposed to crash? It doesn't crash in current trunk build at least.
Comment 4 Bob Clary [:bc:] 2011-08-31 13:53:15 PDT
Martijn, are you using a debug build?
Comment 5 Martijn Wargers [:mwargers] (not working for Mozilla) 2011-08-31 15:00:16 PDT
No, is it only crashing in debug builds?
Comment 6 Bob Clary [:bc:] 2011-08-31 18:01:21 PDT
Yes, the ABORT is a debug only fatal assertion.  I think you need 0 to see the abort. I just reproduced on Mac and Windows beta, aurora, nightly.
Comment 7 Mats Palmgren (:mats) 2011-10-10 08:37:25 PDT
The unconstrained height seems intentional, it comes from here:
I'm hitting this a lot when fuzz testing with cross_fuzz, so let's make it
into an assertion for now...

wallpaper: assert instead of abort

jwatt is a better reviewer for SVG reflow interaction.
Comment 10 Jonathan Watt [:jwatt] 2011-10-18 03:22:10 PDT
Mats, I'm having trouble getting crossfuzz to hit this abort. Do you have a stack handy? I'd like to see if there isn't an simple cause and easy fix before checking this patch in.
Comment 11 Bob Clary [:bc:] 2011-10-18 06:28:04 PDT
jwatt: see the test case.
Comment 12 Mats Palmgren (:mats) 2011-10-18 07:44:30 PDT
jwatt: the profile you use for cross_fuzz testing needs a few prefs:
"block popup windows" = off
"open new windows in a new tab instead" = off
"allow scripts to" (Content/JavaScript Advanced dialog): turn on all
"slow script warning" = off

The root cause seems to be that DocumentViewerImpl::SizeToContent() does an
intentional unconstrained height reflow:
3260   nsresult rv = presShell->ResizeReflow(prefWidth, NS_UNCONSTRAINEDSIZE);
3261   NS_ENSURE_SUCCESS(rv, rv);

Let me know if you can't reproduce it with the attached testcase and I'll
dig up the exact stack.

Reproducible in 10-20 seconds in m-c debug build on WinXP using this URL:

OK, but this shouldn't be too hard to fix for real.
Comment 15 Jonathan Watt [:jwatt] 2011-11-01 03:27:26 PDT
David added the NS_ABORT_IF_FALSE in

Any thoughts on this David?

Pushed the wallpaper to inbound:
To whoever merges that to mozilla-central - please leave the bug open.
