Agreed, we (worker folks) should go investigate this further - it sounds like we may be getting lucky and we have a platform that can repro the crash more frequently.
I just wanted to mention that the main thing in the system that exercises the platform-specific thread/locking infrastructure is workers. If there are any synchronization bugs on a platform (or in a specific part of WebKit) they'll primarily show up as failures in Worker tests. I don't think that's what is happening here, but it's something to keep in mind. -atw On Mon, Mar 29, 2010 at 6:10 PM, Eric Seidel <[email protected]> wrote: > From my experience watching the bots, I would say the Qt build is > relatively stable, so I suspect it's just good at reproducing this > crasher. > > The Qt build is nice that it produces stack traces for every crash. > Sadly their useless until > https://bugs.webkit.org/show_bug.cgi?id=33654 is fixed. > > On Mon, Mar 29, 2010 at 5:47 PM, Drew Wilson <[email protected]> wrote: > > I'll also note that a disproportionate number of those bugs are happening > on > > the Qt build.
