On OS X 10.9.5 my bash shell has the following environment variable set:

__CHECKFIX1436934=1

What is the purpose of this value? I am surprised there is no record of anybody asking this before.

    See discussions.apple.com/thread/5559451, no answer there either. Interesting... – nohillside Oct 4 '14 at 20:58
  • I have __CHECKFIX1436934=1 in my ENV too. I note that the few search results that I find for this include it as part of programmers asking for help and listing their ENV related to the Go language, Python, SublimeText or Brew. I have all of these installed. – Lee Joramo Oct 8 '14 at 17:04

It comes from launch services, specifically this binary

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/LaunchServices

and that environment variable seems to be inherited by many processes, as you can see with ps -Efax

1436934 looks like the number of digits in recent Apple "radar" bug numbers, so perhaps it refers to some value used internally for testing.
