Segfault if compile the .c source code

[FrancescoLucarini]

Hey Milo do you have any clue why the binary crashes despite the fact that gcc doesn't warn about anything?

Hi Francesco,

could you send me the steps to reproduce this problem ? Thanks.

[FrancescoLucarini]

gcc -o sandbox sabdbox.c

./sandbox

Segmentation Fault

[FrancescoLucarini]

If I run
./patch.sh
./sandbox

./sandbox: /home/heap-nman/test/house_of_gods/Libc.so.6: version 'GLIBC_2.34' not found (required by ./sandbox)

You need to compile the sandbox in an older environment. I was using a 17.10 Ubuntu VM in order to compile it. That's the reason why this repository comes with a prebuilt binary :)

Edit: patch the binary's runpath and interpreter with patch.sh after every recompilation of sandbox in order to use custom libc and ld.

Oh ok thanks did you used any special flag on gcc or is actually like the mine the command?

[Milo-D]

Nope, I did not use any special flags for compilation.

Feel free to close the issue if you have no further questions.
