pycharm debug is not working

Hi, more information is welcomed. How exactly do you reproduce the issue? Which code do you run (provide code snippet)?

Sorry for jumping on this thread, but I am also facing same issue while debugging:

Below is the stack trace I am getting:

When I run this program, I am getting correct output:

Here is my fib program, but IMO this has nothing to do with code I am running:

fibonacci.py:

"""Implement a function recursively to get the desired
Fibonacci sequence value.
Your code should have the same input/output as the
iterative code in the instructions."""

def get_fib(position):
    if (position == 0):
        return 0
    elif position == 1:
        return 1
    else:
        return get_fib(position-1) + get_fib(position-2)


# Test cases
print(get_fib(9))
print(get_fib(11))
print(get_fib(0))

I wonder what project interpreter are you using? 

Do you get the issue if you debug a one-line script like `print('hello world')`?

I am using Python 3.6 interpreter. Below is screen shot of interpreter settings. But when I change interpreter to 2.7 i.e. I am not getting error in debugging.

I can reproduce same issue with one-line script `print('hello world')`.

Very strange. Seems very similar to this issue: https://youtrack.jetbrains.com/issue/PY-31228

Do you get the same issue if you rename your script file to something else?

Do you get the issue if you create a new interpreter (with a new virtualenv for example)?

Just for record, my issues was same as the one shared in above link i.e. https://youtrack.jetbrains.com/issue/PY-31228
