Trying to build glibc on a modern Fedora just results in the build hanging. I can see "make" consuming 100% CPU, but not outputting anything. Seem like we're triggering a bug that causes it to be stuck in a loop. The last line we have before this is: > mv -f /local/home/ossman/devel/cenbuild/repo/rpmbuild/BUILD/glibc-2.12.2/build/tls.makeT /local/home/ossman/devel/cenbuild/repo/rpmbuild/BUILD/glibc-2.12.2/build/tls.make Seen with make-4.4.1-6.fc40.x86_64.
