On latest 3.3 alpha builds, both on OsX and Windows, I am getting a crash on Import of a curve alembic file (just do a File>Import>Alembic on it).
This maybe started happening two weeks ago (I think it worked fine on a build from 6/28, but crashed on a build from 6/30 and there onward).

Pretty sure it is related to some internal conversion to the new curve type. Here is the stack trace from the crash (on today's build).

Try with this simple abc file (exported from Houdini):
crashTest.abc
(Just to be clear, start from an empty blender session and simply do File>Import>Alembic on that file)

Thanks for the report. Attached alembic loads fine here.
Can you check again in latest 3.3 build: https://builder.blender.org/download/daily

Confirming it crashes with today's official experimental 3.3.0 alpha build from blender.org.

This crash, similar to dereferenced memory, can be caused depending on the garbage in the memory. To check, you need to run the program several times. I can get 1 correct out of 3 times and 2 failures

As I said also, this Alembic file did not generate any crash on fresh builds from master branch source from 6/28, but then crashes started happening from 6/30 on (though I did not test/rebuild on 6/29).

Try to open the file several times, undo the action or reopen the program and do it
The whole beta reproduces the error, from the versions that I have

Exactly. These are likely due to some relatively recent code changes in master branch (between 6/28 and 6/30).
