I'm currently working on a project that uses both llvm/clang and Boost
code. I came across this;

http://www.mail-archive.com/[e-mail]/msg26065.html

When searching for license compatibility information. It looks like LLVM
uses Boost code in their ADT (containers) library. Oddly, they have
since removed Boost attribution, despite the fact that
the ADT OwningPtr seems to be a modified version of Boost scoped_ptr.

https://llvm.org/svn/llvm-project/llvm/trunk/include/llvm/ADT@44161
introduces an import of Boost's scoped_ptr

svn checkout
https://llvm.org/svn/llvm-project/llvm/trunk/include/llvm/ADT@45274
removes Boost scoped_ptr and introduces OwningPtr. Glancing over or
diffing the two files reveals a lot of similiarities.

I'm possibly being a bit nitpicky here.
