System Information
Operating system: Linux-6.0.12-76060006-generic-x86_64-with-glibc2.35 64 Bits
Graphics card: AMD Radeon RX 5700 (navi10, LLVM 14.0.0, DRM 3.48, 6.0.12-76060006-generic) AMD 4.6 (Core Profile) Mesa 22.2.0

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: Unknown Unknown, hash: 2ae9526cd973867d46c7a51054be01ae7f26043b
Worked: (newest version of Blender that worked as expected)

Potentially caused by: 076a33c

Short description of error
If the node was not the top one in the draw order (there are other nodes that overlap it), clicking on that node's socket to call the Viewer node's causes a crash.

Exact steps for others to reproduce the error
In debug build:

  1. Create new node tree (Geometry nodes or compositor).
  2. Create 2 random nodes.
  3. Click on first one. Now this node are on the top of space for drawing.
  4. Click on the socket of last one node for create Viewer (CTRL-SHIFT-click).
    Expected crash.

@HooglyBoogly Apparently, the composer tree does not have an initialized list of socket positions, if you follow the description

Click on node socket cause re-sorting nodes that clear socket positions. But redrawing didn't happening due to operator doesn't not finished yet and trying to get socket positions.
Possible solutions that i can see:

  1. Call another one node space redrawing after click but before other operator parts.
  2. ensure_socket_locations
  3. Do not cause sorting before other steps.
