Infinite loop at the end of file makes pytype output name-error with global lambda referring to a global variable #1842
Open
Description
Consider the following file
b = 1
lam = lambda: bThis passes pytype without problems.
However, adding an extra while loop at the end:
b = 1
lam = lambda: b
while True:
passI now get an error:
jik@hostname:~/projects/test$ pytype --version
2024.10.11
jik@hostname:~/projects/test$ pytype simple.py

It passes again if I replace the pass by break or if I change the while True to while False/if True/if False, so I guess there's something particular with the infinite loop that confuses pytype.
