There is no crash report of a 32 bit Nightly with build id 20180918xxxxxx.
I couldn't reproduce this crash with a 32 bit Nightly on 64 bit Windows.

If I go back another day I find this:

This seems like it's just an OOM, maybe caused by WebRender's additional memory usage. That would also explain the 32/64bib difference. However there doesn't seem to be anything WebRender specific from the crash report. Can you ensure that you can reproduce the crash with WebRender on and can you take a memory report before the crash?

Until we know more, it's hard to say if this should block.

Sorry for forgetting to add the crash report. Just to know, it's the report you already added in comment 3. I managed to create a Cleopatra report, for more details please click on this link: https://perfht.ml/2MTadeg
