--- Comment #19 from Andreas Krebbel <krebbel at gcc dot gnu.org> --- koriakin stands for Marcin Kościelnicki who implemented LLVM sanitizer support for z as part of a bounty. Ulrich Weigand led the discussions with him. CC'ing Uli. My personal opinion is that support of older Glibcs is not important in that case. All relevant distros for z already have a Glibc with that symbol and asan is new feature. As a debugging tool I think asan is a special case also regarding ABI compatibility. We probably do not want to export the internal symbol and make it part of the ABI because of a single user. I think adding a comment to Glibc code making people aware that this needs to be kept in sync with libsanitizer would be sufficient.
