decompyle failure

[pfremy]

Description

Decompyle3 failed at decompiling some code, where uncompyle6 was successful.

That's too bad because the generated code is of higher quality.

How to Reproduce

See attached sources:
logh_utils.zip

I included the pyc file, the uncompyle3 output, the decompyle6 output.

(.env) C:\work\logh_home\log_enhancer.exe_extracted>python ..\python-decompile3\decompyle3\bin\decompile.py C:\work\logh_home\log_enhancer.exe_extracted\src\logh_utils.pyc  1>C:\work\logh_home\log_enhancer.exe_extracted\src\logh_utils.py

# file C:\work\logh_home\log_enhancer.exe_extracted\src\logh_utils.pyc
# Deparsing stopped due to parse error

Output Given

L. 82 0 BUILD_LIST_0 0
