this is the reply i got some days ago about this problem (building git
from gentoo x11 live overlay):

Hi Beso,

you seem to be using the Gentoo x11 overlay, which is applying a
version of the socket handoff patch.

Since commit cebd582a (allow compile-time setting for XCB queue buffer
size) the patch that adds the missing members to _xcb_out is applied
in the wrong place, namely the _xcb_in structure. You can fix this by
changing a line in
xcb-0004-Support-handing-off-socket-write-permission-to-exter.patch.
Look for

char queue[4096];

and change to

char queue[XCB_QUEUE_BUFFER_SIZE];

I'm cross-posting this to the xcb mailing list as well as the issue
affects the recently posted version 3 of the patchset as well.

Cheers,

Magnus
