System Information
WIN 7 PRO,
NVIDIA QUADRO K2200 4GB

Blender Version
2.79.4
Official release and daily as of May 3rd both have this issue.

Short description of error
Crash to desktop when undoing Boolean operation with mirror modifier.

Exact steps for others to reproduce the error
Appended file: crash_boolean_undo.blend
Does not work with saved file. Should be:

- set modifier to difference
- Apply modifier
- del some vertices
- Undo

Video; crash_boolean_undo.mp4

Full trace:

Add mirror modifier to object as difference (move object from centre so visible)
duplicate - if move keep coplanar faces
add boolean modifier (and move to top, set cutting object)
apply boolean
erase a few vertices
undo until crash (breaks at "apply" stage of boolean mod)

Only got it to crash once (unfortunately without debugger running) -- cannot reproduce now though...

blender.crash.txt

Though a bit speculative, I assume this has to do with the UNDO refactor (seeing BKE_undosys_step_undo_with_data_ex in the crash log...)?
I'll try to get it to crash again, but seeing the relation with UNDO, I'll assign @ideasman42 for now...

Can't redo this bug in 937731dff1af4910dc94646904106432c14b2042, but couldn't redo in c72a204001a either. @VenomirOK could you check if this is fixed in 2.8?
