It appears that the post-fork hooks for malloc(3) are somewhat broken such that when a threaded program forks, and then its child attempts to go threaded, it deadlocks because it already appears to have locks held. I am not familiar enough with the current libthr/libc/rtld-elf interaction that I've been able to fix it myself, unfortunately.
I discovered this today upgrading my work box from 7.0 to 7.1, but I can easily reproduce it at home on a stale -CURRENT as well. Testing on an OS X box to make sure, the regression test does exit 0 there. Has anyone happened to have fixed this already locally? -- Brian Fundakowski Feldman \'[ FreeBSD ]''''''''''\ <> gr...@freebsd.org \ The Power to Serve! \ Opinions expressed are my own. \,,,,,,,,,,,,,,,,,,,,,,\
