Planning to restart the system at 10:30PDT today (August 20,2018). We will post a

Hi, We need to upgrade our Jenkins instance on Green Dragon. We will do so this evening, Wednesday the 7th at 18:30 PST. Email and IRC notifications will be down for a bit after we bring the system back up to allow time for testing. We will notify the list once we are back in full operation. Thanks for your time.

Hello, We have resolved the instability issue with Green Dragon and have re-enabled IRC and email notifications. If you have made any commits within the previous twenty four hours, it would be greatly appreciated if you would check the build status on Green Dragon to see if your commit may be responsible for some of the build and test failures we are currently seeing on the bots. Thank you and

I have added a Jenkins check for this test, which explains why it fails on some builds. Can we change the test to keep its output? Will it just be blank anyways? > On Jan 20, 2016, at 1:23 PM, Kostya Serebryany <kcc at google.com> wrote: > > The test fails again:

Ah ha!

Hm, I tried to reproduce this as well, but unsuccessfully. From the crash report: EXC_I386_GPFLT means we’re dereferencing a non-canonical pointer, in this case “0x00486000000025df”. This happens at wrap_OSSpinLockLock+17, which is just after the prologue and just after calling cur_thread(). So I’d say it happens when we’re dereferencing the pointer returned by cur_thread(). On OS X, we’re
