Preprocessed source as generated by -freport-bug, third test case, gcc 5.1.1
svn 223417

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.
