Checklist
- I am confident this is a bug in CPython, not a bug in a third-party project
- I have searched the CPython issue tracker,
and am confident this bug has not been reported before
CPython versions tested on:
3.11, 3.12
Operating systems tested on:
Linux, Windows
Output from running 'python -VV' on the command line:
No response
A clear and concise description of the bug:
Consider the following codeblock that works correctly when interrupted by ctrl+c.
try:
while 1:
pass
except KeyboardInterrupt:
print("Exception handling works!")
Exception handling works!
Now we push the pass
into the same line and suddenly our try-except is ignored entirely:
try:
while 1: pass
except KeyboardInterrupt:
print("Exception handling works!")
Traceback (most recent call last):
File "/home/panta/issue.py", line 2, in <module>
while 1: pass
KeyboardInterrupt
This was quite a surprise to me because I naively expected both approaches to emit the same bytecode (except with different line info).
