I have tried this on two different systems. The current hypothesis is that it is due to a race in the build system. At the point where the error occurs, libgcc.a (an alias of libcompiler_rt.a) should already have been built, with the __aarch64_* symbols in it. In the logs from ci.freebsd.org <http://ci.freebsd.org/>; you can see that libcompiler_rt.a has already been built, and installed into ${WORLDTMP}. So it's still a mystery why this error even occurs. -Dimitryhome | help
