If you Google that number, https://github.com/nico/lssym is the first result
(and I see you’ve just made changes to the README today). Ha!

cctools’ misc/strip.c tells you a little bit about this, and the number shows up
in a few other files in cctools for details. I see it in cctools-839 from Xcode
4.6, so it should still be in there. If you’re seeing a difference comparing
between local runs and the bots, are you running an Xcode DP locally?

:-)
I'm running 4.6.3 locally. Weird.

[Mark Mentovai, 2013/09/14 04:23:37]

OK, but be aware that 64-bit binaries are gonna have 16 hex digits here. This
will work, but I’m just pointing it out because you don’t NEED eight Xs here.
You could get away with one or even zero.

[Nico, 2013/09/14 04:30:42]

Done.

[Mark Mentovai, 2013/09/14 04:23:37]

But you’re not testing that the numbers are the same now. This comment should be
revised.

[Nico, 2013/09/14 04:30:42]

Done.
