I can reproduce this issue.  It's not that it can't create the socket,
actually it does so, but for some reason it calls select and, when select
returns, it decides to clean up and exit.  It's tricky to debug because
ssh-agent has no debug mode and for some reason it doesn't occur under
strace.

For the time being, the workaround is:

  $ eval `ssh-agent -s`
