492667 - Mochitest freezing on test_HTMLBodyElement07.html

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[David Mandelin [:dmandelin]]

When I try to run Mochitest on my own machine, it "freezes" on /tests/dom/tests/mochitest/dom-level2-html/test_HTMLBodyElement07.html. That is, the browser stops doing anything and stops responding to input. The status bar shows "Waiting for localhost..." or "Read localhost" with a partially filled progress bar. In the activity manager, xpcshell is shown as "Not Responding".

May be related, might not be, but running this test locally segfaults, on Ubuntu, AMD64.

hg bisect points the finger at http://hg.mozilla.org/mozilla-central/rev/d51a8d3295d0.

gdb gives the following stacktrace:

[Jeff Walden [:Waldo]]

Probably a separate problem; I'm pretty sure dmandelin doesn't have gcj installed on his system.  That's part of why we have a test plugin and don't just use the third-party ones directly... :-\

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
