3 months ago I have similar problems with multiple opcodes over different pycfiles, in one case the "Unsupported opcode" isn't even used in the pyc anywhere (confirmed in a hex editor), and it's always an opcode that is supported (exists in ASTree.cpp and should not be falling through into default: case which prints this message.)
This issue has actually rendered the pycdc tool itself unreliable for me (sometimes it works, sometimes it doesn't).
What is interesting is in every case this occurs the pycdas tool works correctly and does not emit any <INVALID> entries, as a result I have stopped using pycdc in favor of pycdas since the disassembler always works correctly.
Seems like a bug. I believe a similar report has been made by other users recently:
- https://github.com/zrax/pycdc/issues/477
- https://github.com/zrax/pycdc/issues/466
- https://github.com/zrax/pycdc/issues/366 <-- this one seems to have some additional information, submitter made an attempt to debug the issue and found the TOS in ASTree looked unusual.
..because I can't publicly share any of my test inputs where I have observed this I have hesitated to file a bug, but it seems it's not just me running into whatever this is.
Seems like an AST bug.
