Crashed while drawing a way.

[TarasD]

What steps will reproduce the problem?

I don't know what steps can reproduce it. I was creating a way and then pressed backspace twice to undo the last two nodes (of three that were drawn). It appears it may have tried to snap to an existing nearby way at the moment the crash occurred.

What is the expected result?

Undo the created nodes.

What happens instead?

Crashed after undoing two of the three nodes of the new way.

Please provide any additional information below. Attach a screenshot if possible.
