--- Comment #3 from Damjan Jovanovic damjan.jov@gmail.com --- Patch committed, resolving fixed.
I should note, for this bug to occur, the hostname from gethostname() must be unresolvable by getaddrinfo().

--- Comment #4 from Alex S iwtcex@gmail.com --- I can't help but notice, the patch doesn't touch the code changed by that supposedly bad commit. Either this is a botched bisection or there might be more than one issue.

--- Comment #5 from Damjan Jovanovic damjan.jov@gmail.com --- I can't explain it either, but the commit before the regression definitely doesn't crash, and backporting the fix to the regression definitely fixes it.
