I did try adding that patch to my build, but it did not change the 
result. The compile failed in the same place. It may be that because I'm 
trying to compile a release and not nightly, the thread_local stuff is 
not turned on. You mentioned enabling the "unstable" feature flag. I 
don't know to to do that.
