My system is OS X El Capitan (10.11.4). I'm using an installation built with a successful bootstrap from bug 564814. Using USE=gmp and linking against dev-libs/gmp-6.0.0a creates (at least) a broken expr on my system: $ /opt/gentoo/bin/expr 262144 / 4 Segmentation fault: 11 That breaks the check for maximum length of command line arguments in configure, which may also break libtool. When I try to build anything with libtool after that it fails to link everything and I (sometimes but not always) get errors like: ld: symbol(s) not found for architecture x86_64 See for example bug 578468 and bug 578566. It seems to be fixed with dev-libs/gmp-6.1.0. Reproducible: Always
synced, thanks
