@Alex Crichton you are using jemalloc without background threads right ?
to test the hypothesis of the orphan child threads you might want to hook up a
panic! that sleeps for a couple of seconds and see if that fixes the issue
@gnzlbg I don't think so just yet, I wasn't sure how to both compile it in and enable it (just trying to get it to land atm)
i'll send a PR to jemallocator with background thread support today - I discovered a couple of bugs in jemalloc upstream that have to be worked around in osx, musl, etc =/
@gnzlbg ah ok, thankfully it should now be super easy to update jemalloc in rustc!
ideally this'd just be a
cargo update to get a new version
yeah, thank you for that
