1015611 - --enable-debug crashes around nsIFrame::AssociateImage on opening www.newegg.com

Status: VERIFIED DUPLICATE of bug 975397

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Jan Beich]

The following backtrace is from unmodified Beta30 source. I'm still trying to find less heavyweight site that triggers the crash or guess why it doesn't happen on Aurora31.

# .mozconfig
ac_add_options --disable-dbus
ac_add_options --disable-libnotify
ac_add_options --disable-pulseaudio
ac_add_options --disable-webrtc
ac_add_options --enable-debug
ac_add_options --enable-alsa
ac_add_options --enable-gstreamer=1.0

$ firefox -no-remote -P test2 www.newegg.com
