I cannot reproduce this with either the latest stable or current development versions of Blender.

Either in local builds or in a build from https://builder.blender.org/download/daily/

Can I see the crash call stack to get an idea of what's going on?

Unfortunately, without being able to replicate the problem, I am unable to investigate.

ASAN does not work neither on Windows nor on Mac.

I tried different asserts but nothing strange was revealed.

EDIT:
I found an error in the size of the doubles_buffer buffer!
