System Information
Windows 10, Radeon HD 4800 series

Blender Version
Broken: 2.79.3 - 7e4c23e
Worked: works OKAY in 2.79a release

Short description of error
Blender crashes after 2-3 attempts of undoing a move of a curve (which is shrinkwrapped onto another object)

Exact steps for others to reproduce the error
So, here's how it crashes for me:

Move Roots.001 object (in object mode)
Undo (it mostly works, but crashes sometimes aswell)
Move Roots.001 again
Undo ( this is where it crashes most of the time for me)

Okay, guys, sorry, i think i found the problem. That's the Curve Tools addon, if you have the addon ribbon (named "Curve tools 2") rolled open in Tools panel (T), blender crashes. If you roll that scroll down (or close the tools panel), you can undo as much as you want, just as long as you don't see curve tools opened in tools panel.
