Alembic export crashes Blender.

Hi, I have a problem with exporting mesh to abc file. Blender crashes in similar manner to when trying to render file containing AN tree.

blender crash log:

I can render the animation form bash, so should also be able to export mesh using python scripting run form cli, but it's somewhat strange that exporting meshes also crashes blender...
