Does it happen with default cube scene?

@dr.sybren , adding it on your radar ;)

You would need to create a fluid sim with a resolution of 240. I could get it to export OK with a resolution of 200 and dropping the number of frames from 200 to 50 in the animation.

Please attach a blend file that lets us reproduce this issue.

No problem, I'll upload one later.

bd stream.blend

I've uploaded a blend file, you'll need to bake out the simulation before trying to export it as an Alembic file to see the issue.

Cheers

baking took forever, and i needed the debug heap (asan will probably catch it on linux) to trigger the issue but here's a stackdump

Blender is also crashing each time I try to export a fluid simulation as an Alembic file. My simulation is about 500 frames and resolution of 65. I'm on Windows 10, Blender 2.79b. Attached project file for testing (needs baking, shouldn't take too long). Only by limiting the export to about 20 frames I'm able to avoid the crash.
