Description Florian Weimer 2016-05-17 08:38:12 UTC 
Please backport this ASAN upstream fix:

  https://llvm.org/bugs/show_bug.cgi?id=27310
  http://reviews.llvm.org/rL269633

glibc 2.24 (to be released in August 2016) will likely require this ASAN fix, otherwise all ASAN binaries will break.  It would nice to have point releases by then, or at least the backports on the relevant branches.
