Consider simple script:
```
for i in range(1):
    import pdb
    pdb.set_trace()

x = y + z
```
After running it and pressing 'c' to continue:

```
test$ python test.py
> /Users/bedrich.pisl/test/test.py(1)<module>()
-> for i in range(1):
(Pdb) c
```
I get error, but with wrong error line
```
Traceback (most recent call last):
  File "/Users/bedrich.pisl/test/test.py", line 1, in <module>
    for i in range(1):
NameError: name 'y' is not defined
```
The error is actually on line 5 not 1.

I tried this on current main branch, and I cannot reproduce the problem there.
