IRC, OFTC, #debian-hurd, 2011-07-21.

    <youpi> there's one known issue with pthreads
    <youpi> you can't dlopen() it
    <youpi> which also means you can't dlopen() a module which depends on it if
      the main application hasn't used -lpthread already
    <youpi> (so as to get libpthread initialized early, not at the dlopen()
      call)
    <lucas> I get this while building simgrid:
    <lucas> cd /home/lucas/simgrid-3.6.1/obj-i486-gnu/examples/gras/console &&
      /usr/bin/cmake -E create_symlink
      /home/lucas/simgrid-3.6.1/obj-i486-gnu/lib/libsimgrid.so
      /home/lucas/simgrid-3.6.1/obj-i486-gnu/examples/gras/console/simgrid.so
    <lucas> cd /home/lucas/simgrid-3.6.1/obj-i486-gnu/examples/gras/console &&
      lua /home/lucas/simgrid-3.6.1/examples/gras/console/ping_generator.lua
    <lucas> lua:
      /home/buildd/build/chroot-sid/home/buildd/byhand/hurd/./libpthread/sysdeps/generic/pt-mutex-timedlock.c:68:
      __pthread_mutex_timedlock_internal: Assertion `__pthread_threads' failed.
    <lucas> Aborted (core dumped)
    <youpi> that's it, yes
    <youpi> (or at least it has the same symptoms)
    <lucas> it would need fixing in lua, not in SG, then, right?
    <youpi> yes
    <lucas> ok, thanks
