not sure whats going on on your PC... sorry are you using latest bits of the tool? etc

here is what I'm getting on your input:

AutoForward_Telegram.pyc.cdc1.txt

[greenozon]

abc.pyc is hitting the Unsupported opcode: DICT_MERGE issue

but decompiles 99% the rest..

[steklyashka33]

@greenozon could you tell me what needs to be done to properly install pycdc and repeat your success?

[greenozon]

for the beginning - build binaries from latest sources?

[steklyashka33]

I am using the latest version of pycdc

[steklyashka33]

I used this link instruction for linux but I can use windows

[greenozon]

the steps in above link IMHO looks over-complicated I"ve tried to bring up binaries on Linux (Ubuntu 20.04) and here is my output:

git clone  ...
cmake . 
make
 
./pycdc ./AutoForward_Telegram.pyc 
# Source Generated with Decompyle++
# File: AutoForward_Telegram.pyc (Python 3.11)

import os
 
......... (full text shown)
 
 


./pycdc abc.pyc 
# Source Generated with Decompyle++
# File: abc.pyc (Python 3.11)

Segmentation fault (core dumped)
 
 

I'm not able to see the crash under Windows...
