Worked: (newest version of Blender that worked as expected)

Short description of error
Hi All, for last 2 days, geometry node in my nightly build blender is crashing a lot mostly when I try to create noodles from a node socket. It's basically unusable.
Attaching the file I am working on. Thanks!

Exact steps for others to reproduce the error
Drop a "Realize Instance" node in the node tree at the end as in screenshot.

Thanks for the report. I can confirm.

In a Debug build we reach this assert:

BLI_assert failed: D:\Dev\BlenderDev\blender\source\blender\blenkernel\intern\curve_eval.cc:430, curves_to_curve_eval(), at '0'
  This line of code is marked to be unreachable.

It looks like the realize instances node is taking the curve_type attribute and moving it from the curve to the point domain. I'm not quite sure why yet; the code is quite complicated.

I think it will be easier to port the node to the new Curves data-block honestly, rather than fixing this bug and then porting it later.

Actually I was quite wrong. This is the system working as intended, but curve_type isn't marked as a builtin attribute. The fix is simple.
