The code below causes a segfault on clang++-4.0 on Ubuntu.

class A {
  template<class T>
  A(const T& a) { }

  A& operator=(const A& a) { return *this; }

For me, it doesn't segfault, but simply complains about the recursive template
exceeding the maximum instantiation depth:

Yeah the code has "issues" and is not valid C++, but the segfault is still
invalid behaviour.

I've tested on Ubuntu 16.04 and 17.04, using  packages of clang++-4.0 from
http://apt.llvm.org/ and both installs segfault. I have a segfault with clang++-
5.0 as well (see below).

There's nothing "unusual" about my system configuration and I constantly
compile plenty of code using clang without issues so its not systemic.

Quuxplusone commented 7 years ago 
To prove its not my system, I set up a github repository with the test case:
https://github.com/toastedcrumpets/clang-bug-34134

I then use Travis CI to build the test case on a range of fresh clang installs:
https://travis-ci.org/toastedcrumpets/clang-bug-34134/builds/263262653

clang 3.6, 3.7, 3.8, 3.9, all fail with the correct template recursion error.
clang 4.0 displays the segfault.
clang 5.0 fails to install so no result there (issue with travis)

I can reproduce with svn head
