Minimal example to reproduce:

>>> with open('', 'w') as fp:
...     fp.write('f"{a b}"')
>>> import f_bug
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<fstring>", line 1
    (a b)
SyntaxError: invalid syntax

Here we see in track trace "<fstring>" and line number in erroneous expression in f-string, but no "" and line number in it.

I'm pretty sure there's already an issue for this, but I don't have time to search for it now.

This is not an easy problem to solve. I've been working on it on and off for almost a year. I'll eventually get to it, but the changes are pretty invasive.
