Hi Shawn, I've tried reproducing, using WITH_LLD_BOOTSTRAP and WITH_LLD_IS_LD, but buildworld finishes without issues for me. This is with explicit __MAKE_CONF=/dev/null and SRCCONF=/dev/null environment variables, so everything else is at its defaults. Do you have any other particular settings, like modified default CFLAGS or LDFLAGS, either in your share/mk/*.mk files, or somewhere else? -Dimitry
