[Bug 1610168] Re: error: 'basic_string<_CharT, _Traits, _Allocator>' is missing exception specification

[Simon Quigley]

Hello!

Could you please indicate which releases are still affected by this?
Also, if you would like to get this in Xenial, which is a stable
release, please follow the SRU policy:
https://wiki.ubuntu.com/StableReleaseUpdates

For now, I'm unsubscribing ~ubuntu-sponsors because it's not clear what
there is to sponsor. Please feel free to resubscribe ~ubuntu-sponsors
once things are clarified.

Thanks!

Title:
  error: 'basic_string<_CharT, _Traits, _Allocator>' is missing
  exception specification

Status in libc++ package in Ubuntu:
  Confirmed

Bug description:
  This is mirroring Debian bug #808086 https://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=808086

  Compiling any source file that includes <string> with clang 3.8 and
  -std=c++11 -stdlib=libc++ results in a compile error.

  While this is a minor bug in Debian (as it doesn't ship 3.8 yet),
  xenial does, and that's a major problem as it makes libc++ useless.
