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.
This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle. Changing version to '25'.
compiler-rt 3.9.1 in f25 has this fix.
