Feature obfuscate_struct_access crash during startup

[sevilS]

How to reproduce:

• HackerNews project: https://github.com/amitburst/HackerNews.git

Using the following configuration:

import omvll
from functools import lru_cache

class MyConfig(omvll.ObfuscationConfig):
def init(self):
super().init()
def obfuscate_arithmetic(self, mod: omvll.Module,
fun: omvll.Function) -> omvll.ArithmeticOpt:
return True

def flatten_cfg(self, mod: omvll.Module, func: omvll.Function):
return True

def obfuscate_constants(_, __, func: omvll.Function):
return True

def obfuscate_struct_access(self, _: omvll.Module, __: omvll.Function,
struct: omvll.Struct):
return True

def obfuscate_string(self, _, __, string: bytes):
return omvll.StringEncOptStack()

@lru_cache(maxsize=1)
def omvll_get_config() -> omvll.ObfuscationConfig:
"""
Return an instance of ObfuscationConfig which
aims at describing the obfuscation scheme
"""
return MyConfig()

Is failing.

If I remove the struct access feature it works fine.
