LLDB always fails during the setenv call

[fnschmidt]

Hello, I would really like to give this a try. However in my case the injection seems to fail pretty early on:

$ killall Dock && sudo scripts/inject.sh min0125
(lldb) process attach --pid 3268
Process 3268 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP
    frame #0: 0x0000000000000000
error: memory read failed for 0x0
Target 0: (Dock) stopped.
Executable binary set to "/System/Library/CoreServices/Dock.app/Contents/MacOS/Dock".
Architecture set to: arm64e-apple-macosx-.
(lldb) settings set target.process.thread.step-out-avoid-nodebug true
(lldb) expr (int)setenv("INSTANTSPACES_MODE","min0125",1)
warning: could not execute support code to read Objective-C class data in the process. This may reduce the quality of type information available.


error: Trying to put the stack in unreadable memory at: 0xffffffffffffff80.

This always seems to happen - i tried this about 20 times, sometimes with and sometimes without killing Dock beforehand
Things I've tried:

• SIP is disabled (csrutil status: System Integrity Protection status: disabled.)
• Adding Terminal and lldb to developer tools (Terminal already was, lldb was not)
• rebooting

Do you have any idea why lldb apparently cannot modify Dock memory?

Hey, I'll have a look at this in my free time - I think I need to update the patches for your macOS version. I am still on Sonoma so cannot reproduce this as easily :)
