Lu" MIME-Version: 1.0 Content-Disposition: inline User-Agent: Mutt/1.8.0 (2017-02-23) This patch changes configure.ac to allow gold 1.14 or above to be used to configire glibc. Tested with CC="gcc -fuse-ld=gold" CXX="g++ -fuse-ld=gold" on Fedora 25 with gold 1.14 (20170623). Gold 1.14 was first released in binutils 2.28. For "make check", I got Error in `/export/build/gnu/glibc-gold/build-x86_64-linux/elf/constload1': double free or corruption (fasttop): 0x00000000008755f0 *** ======= Backtrace: =========
