<pre>Proposed Boost.AFIO has been generating this assertion fail for some time on
clang's >= 3.4 on ARM and Windows that I know of. I had simply been recompiling
clang with assertions disabled or falling back to clang 3.3 and all is well,
however I saw Chandler at C++ Now last week and he got annoyed with me for not
reporting it. So here it is.
I see a number of bug reports with this exact same assertion fail. I'll link
them shortly.
On Windows using the binaries for clang 3.6 from the LLVM website:
Assertion failed: !SpecializedTemplate.is<SpecializedPartialSpecialization*>()
&& "Already set to a class template partial specialization!", file
D:\src\llvm_release_build_3.6.0-final\llvm\tools\clang\include\clang/AST/DeclTemplate.h,
