Short description of error
Node groups do not work correctly

Exact steps for others to reproduce the error

Open attached blend file
render
wait til it has finished & comped
if it is all white, then it has the bug i am experiencing, if you see the rendered image normally, then the node group worked correctly

Ugh, yes, getting a white result - and even got a crash just trying to add a viewer node (after going in and out of group - tab key)…

So, here is how I get it crashing:
*Open the file
*Render (you can even interrupt render after a few tiles if you want)
*Go to node editor
*Enable compo nodes
*instant crash (see asan backtrace below).
