Oops... Works locally. Weird. Need to look into.

In fact, we do not even build the test plugin so it's not a surprise that tests don't work.

Reopen, because it made 3 tests crash on Qt5-WK2:

Regressions: Unexpected crashes : (3)
  compositing/repaint/become-overlay-composited-layer.html = CRASH
  fast/frames/iframe-remove-after-id-change.html = CRASH
  plugins/change-widget-and-click-crash.html = CRASH

Unfortunately these tests work on themselves, but fail if you run all tests.

Have you got any idea what happened?

Any progression with fixing the crashes?

Any progression with fixing? Unfortunately the WK2 bot is still red because of this bug.
------- Comment #8 From 2012-04-20 01:05:18 PST -------
Any progression with fixing this regression? Or do you think if crashes are OK in the trunk WebKit2?

> Any progression with fixing this regression? Or do you think if crashes are OK in the trunk WebKit2?

I tried but I could not reproduce the regression reliably. When I runned tests in  Ubuntu I saw 3 crashes. Not always the same ones. (This is the case on the bot as well.) The strange thing is that: with ulimit -c unlimited + echo core.%p > /proc/sys/kernel/core_pattern I only got one core dump for the whole test session. Seems like the other two crashes detected by nrwt are not real crashes. Furthermore, the core dump I got is unrelated to plugins or plugin process, it's about rendering. After all, I am a bit puzzled about how should I reproduce / fix the problem. Anyway, this is way off topic for this bug. I'm going to file a new.

No, it isn't offtopic. Because your patch caused these crashes.

Repone, since the patch had been rolled out.
