Current Behavior

I'm running a script which automaticaly arrange the containers following some specific rules. The commands given to ipc looks like :

[con_id=94800575960816] focus,move left;[con_id=94800576165168] focus,split vertical;[con_id=94800575774320] focus,move up;[con_id=94800575924928] focus,split horizontal;[con_id=94800575773856] focus,split horizontal;

Reproduction Instructions

This seems to crash with an interraction with fullscreen windows. I'm trying to identify the exact way it occurs.

Environment

Here is a stacktrace from a bug : (not the same as the one in the log, but in the same conditions)

I'm trying to make i3 act as a dynamic tiling WM, and automaticaly rearange the workspace tree when a new window is created.

It operate by :

  • reducing the tree (if a container has only one child, move all the subchild under the grand parent)
  • changing the layout (a splitv container should have a splith child and vice versa)

It preprocess the tree, then create a command throught ipc in order to reorganize all the windows. All the operations are chained in a single command.

I see this error in the backtrace :

#8  0x00007f77d41c6c1a in malloc_printerr (str=str@entry=0x7f77d42c9393 "corrupted double-linked list") at malloc.c:5341
#9  0x00007f77d41ca231 in _int_malloc (av=av@entry=0x7f77d4302c40 <main_arena>, bytes=bytes@entry=448) at malloc.c:3931

The only one commands sent are the one I've given in example :

  • [con_id=…] focus,move {up/left}
  • [con_id=…] focus,split {horizontal/vertical}
