I've downloaded:
~/dwnlds/llvm/3.8/prebuilt $ wget
http://www.llvm.org/releases/3.8.0/clang+llvm-3.8.0-x86_64-linux-gnu-ubuntu-14.04.tar.xz.sig
untarred it, and compiled a simple program:
#include <vector>
int main()
{
std::vector<float > vecf(2);
std::vector<double> vecd(2);
vecf = vecd;
return 0;
}
resulting in, as expected, an indented error message showing the tree:
candidate function not viable: no known conversion from argument
type to parameter type for 1st argument
vector<
[double != float],
allocator<
[double != float]>>
vector& operator=(vector&& __x)
^
However, when compiling a much more complex template program, there's no
tree evident by the indentation:

As you can see from the output, there's only *one* level of indentation
when several levels, reflecting the tree structure, are what I expected.
How do I get the expected indentation?
TIA.
-regards,
