Hi,
with i3-4.17 and i3-4.17.1 from snapshots on amd64 -current, i3 is terminated by
pledge() when using the append_layout feature. The previous package version
4.16.1p0 works fine. The offending syscall is shmget(), dmesg says:
i3[72874]: pledge "", syscall 289
The backtrace looks like this (after rebuilding 4.17.1 from ports tree with
debug symbols):

Here is a minimal ~/.i3/config to reproduce:
# i3 config file (v4)
font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
exec --no-startup-id "i3-msg 'workspace 1; append_layout
~/.i3/workspace-sample.json'"
To be used with this ~/.i3/workspace-sample.json:
{
// stacked split container with 2 children
"border": "normal",
"floating": "auto_off",
"layout": "stacked",
"percent": 0.5,
"type": "con",
"nodes": [
{
"border": "normal",
"current_border_width": 2,
"floating": "auto_off",
"geometry": {
"height": 364,
"width": 644,
"x": 0,
"y": 0
},
"name": "tmux",
"percent": 0.5,
"swallows": [
{
// "class": "^XTerm$",
// "instance": "^xterm$",
"title": "^tmux$"
// "transient_for": "^$"
}
],
"type": "con"
}
]
}
The problem can also be reproduced in version 4.17 and 4.17.1 by running the
i3-msg append_layout from a terminal after i3 has started. In 4.16.1p0 there is
no abort either.
The pledge() call hasn't changed between those versions, also the working and
non-working versions all use the same cairo libs. Looks like some internal
change within i3 is causing this.
Cheers,
Ralf
