            Bug ID: 23348
           Summary: Boost.MultiIndex tests segfault
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++14
          Assignee: unassignedclangbugs at nondot.org

Current tests for Boost 1.58 version of Boost.MultiIndex are segfaulting for
Clang version 3.7.0 (trunk 235724) (-std=c++1y -stdlib=libc++) on Ubuntu 15.04
x86_64, as shown at, for instance:

http://tinyurl.com/m3lmetv
http://tinyurl.com/ldzgsjr

etc. These same tests under the same environment work OK when using either
version 3.5.1 (tags/RELEASE_351/final) (-std=c++1y -stdlib=libc++) or version
3.6.0 (tags/RELEASE_360/final) (-std=c++1y -stdlib=libc++).

I don't have access to the environment to produce a smaller testcase than this.

Also, the very same behavior seems to happen for Clang 3.5 under CrystaX.NET
Android emulator; in this case, thests work for Clang 3.4. A ticket was filed
by CrystaX developers at

https://tracker.crystax.net/issues/908

though I'm suspecting the problem lies in Clang itself, given the similarity
between the two scenarios.
