`.undo` after an "evaluation" (no semi colon) leads to crash

Describe the bug
Doing something like:
int x = 10;
x == 10;
.undo 2
float x = 10;
Works fine, but if you want to evaluate x == 10 (so no trailing colon):
int x = 10;
x == 10
.undo 2
float x = 10;
then you get a crash:

If you insert a ; after your evaluation, then it still doesn't work:
int x = 10;
x == 10
;
.undo 2
float x = 10;
(same crash, but you can .undo 1!)
Expected behavior
I would expect to be able to "undo" evaluations.
To Reproduce
- Build
cling - Input something like:
int x = 10;
x == 10
.undo 2
float x = 10;
- Observe crash

Additional context
I cannot reproduce the crash with the current master, it works for me, could you retry with latest commits ? Maybe @hahnjo knows at what commit exactly this was solved.
When I run the same file for the second time, I also find the following issues：
（the cling git warehouse latest commit SHA-1: a54ec55f322a37f34fc32ec6a9c6a43430045ae7, the llvm-project git warehouse latest commit SHA-1: 11393b396848b418ab6840a7958e3edfa3269d1f）
