To try to find the cause of #8501 (comment), I started a slow valgrind job as JULIA_CPU_CORES=1 valgrind --leak-check=yes ./julia test/runtests.jl &> /tmp/test1.txt, and got lucky and trapped a segfault. The gist is here. It goes on for a long time after that, but I suspect all the important stuff is there.
