Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment:
It is a bug. Compiler explicitly checks if the number of nested "try" blocks
does not exceed the limit of CO_MAXBLOCKS, but it does not count implicit "try"
blocks inserted when your assign an exception in the "except" clause.
try:
...
except Exception as e:
...
is actually translated to
try:
...
except Exception:
try:
e = ...
...
finally:
e = None
del e
So we have double number of nested "try" blocks.
