4 months ago I tried to reproduce this, but failed due to all sorts of things not being installed and setup correctly on my machine. I needed to import pwnlib as pwn instead of import pwn to get anywhere though, are you sure the snippet is correct?
In any case, I don't quite see where we even have the potential for a memory leak here. Is it vital that your example_program debugging happens within construct? I guess you will want to interact with it somehow in your actual example. Can you verify that the parts of your code where you interact with pwn run independently in the same Python environment you use to render your Scene? I.e., does running
import manim
import pwn
import numpy
example_program = pwn.gdb.debug(["./variable_distribution"], api=True)
example_program.gdb.Breakpoint('main', temporary=True)
example_program.gdb.continue_and_wait()
example_program.gdb.quit()
example_program.close()work for you as intended?

Description of bug / unexpected behavior
I tried to generate a video after a full system upgrade, but manim stopped responding in
self.playofmanim.Scene, and ate all of memory of my laptop.Expected behavior
It should not use so much memory and should give me a video.
How to reproduce the issue
Compile an binary and name that
variable_distribution. The command I used to compile wasgcc variable_distribution.c -g -no-pie -O0 -o variable_distributionCode for reproducing the problem
```py import manim import pwn import numpy class VariableDistribution(manim.Scene): def construct(self): example_program = pwn.gdb.debug(["./variable_distribution"], api=True) example_program.gdb.Breakpoint('main', temporary=True) example_program.gdb.continue_and_wait() stack_view = manim.Rectangle(color=manim.WHITE, width=3, height=5, fill_color=manim.BLUE, fill_opacity=0.75) stack_view.move_to(numpy.array([-4.5, 0, 0])) heap_view = manim.Rectangle(color=manim.WHITE, width=3, height=5, fill_color=manim.BLUE, fill_opacity=0.75) heap_view.move_to(numpy.array([-2.5, 0, 0])) code_view = manim.Code("variable_distribution.c", language="C") code_view.scale(0.35) code_view.move_to(numpy.array([2.5, 0, 0])) example_program.gdb.quit() example_program.close() self.play(manim.DrawBorderThenFill(stack_view), manim.DrawBorderThenFill(heap_view), manim.Write(code_view)) self.wait() ``` `variable_distribution.c`: ```c #includeAdditional media files
