--- Comment #1 from James Almer <jamrial at gmail dot com> ---
While the above file compiles with 4.9.2 and 5.1, the following file fails with
5.1 with a segmentation fault error in the same line (6.0 however also fails
with the tree check ICE).

How about this one? Crashes with segmentation fault on gcc 5.1.1 svn 223417
(ArchLinux x86_64).

With gcc 6.0.0 svn 223906 it crashes with apparently the same tree_check ICE as
the first test case.
I can post that -freport-bug output if needed.

I'm using "gcc version 5.1.1 20150519".
Will recheck with an updated version tomorrow.

That's the one that crashed for me with this new test case. svn 223417 (used
for the 20150519 weekly snapshot).

Looks like a heisenbug. Can't reproduce it when i use the preprocessed output
created by -freport-bug, only when i try to normally compile the file.

If the same happens in your end, you could try (with gcc 5.1.1):

git clone https://github.com/ericniebler/range-v3.git
cd range-v3 && mkdir build && cd build
cmake .. && make alg.partial_sort_copy
