[New-bugs-announce] [issue42634] Incorrect line number in bytecode for try-except-finally

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

The following code, when traced, produces a spurious line event for line 5:

a, b, c = 1, 1, 1
try:
    a = 3
except:
    b = 5
finally:
    c = 7
assert a == 3 and b == 1 and c == 7
