Segfault shortly after joining a multiplayer game

[Francis Herne]

Using the Arch Linux package, 0ad-a20-6, on x86-64.

I joined a 2v2 Skirmish game via the lobby. Seconds after the game started, I added one woman and five infantrymen to the civic centre queue.

The game segfaulted around the woman (first unit) spawned, may be completely unrelated.

No debug symbols, sorry.

Sounds like #4053 to me. Please test the new release Alpha 21 which should have that "random crash with gcc6" issue fixed and reopen this ticket if so.
