Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Windows 7 x64 has the crash, but the node not updating also happen on Linux.
Blender Version
Broken: 2.78a
Short description of error
When trying to reload a librairy with node groups, Blender either crash or doesn't update the node.
Exact steps for others to reproduce the error
Open both files : bug reload with linked node group.blend and bug reload node group.blend
Remove one input in the node group from "bug reload node group.blend"
In "bug reload with linked node group.blend", right click on the lib and reload the lib. Blender crashes (on windows, but not always it seems) or the lib is not updated.
Changed status to: 'Open'
Added subscriber: @bliblubli
Reloading the whole Blend file works as expected.
Did you check this is still happening with master?
yes still happen:
@mont29 but only on windows, Linux just doesn't really reload/update the node group.
Issue confirmed, crash happens in blend writefile code (for undo step right after reloading lib)…
Think there are more than one issue here though, nodes are really tricky to handle correctly :/
PS: release builds on linux tend to be much, much robust to invalid memory access than windows ones, but here with debug build and asan enabled, it crashes everytime ;)

@mont29 thanks for the fix. It is also my feeling that Linux Builds crashes much less. At least in this case, windows help get a cleaner code :)
