GUIHorn uses 55 GB of RAM

[Anonymous941]

Describe the bug
When analyzing a large binary, I have to make an absurdly large swap file (100 GB) or else it will run out of memory. The combined RAM + swap usage is 55 GB, which seems much higher then intended

To Reproduce
Steps to reproduce the behavior:

1. Use GUIHorn
2. See error

Expected behavior
It uses a reasonable amount of RAM

Desktop (please complete the following information):

• OS: Ubuntu

I need more details ... what is the definition of "large program"?

I need more details ... what is the definition of "large program"?

It's a ~20 MB firmware image with 430,939 symbols and 49,683 functions. I can send it if it helps (it's released here, but it uses an obscure compression scheme so I can decompress it for you). It just seems that even parsing a large program shouldn't use 50 GB of RAM, and the memory is not freed after the script finishes
