make -j24 test
My computer is slow but has many cores. I find several hundred tests fail "bad stderr" when I set the environment variable:
export MAKEFLAGS=-j24 make test
I'll update with the list of failing tests in a few hours when I'm done running the testsuite serially. But one is T3307. It even fails when run by itself like:
export MAKEFLAGS=-j24 make test TESTS="T3307"
But otherwise passes if
unset MAKEFLAGS make test TESTS="T3307"
