Possible M1 incompatibility with macOS Monterey (12.0 Beta)

[QuietRocket]

OS: macOS Monterey 12.0 Beta
VSCode version: 1.57.1
Extension version: 1.6.4
Compiler: rustc 1.53.0 (53cb7b09b 2021-06-17)
Build target: stable-aarch64-apple-darwin

Hi. I'm trying to debug a simple Rust hello world with the following simplified (non-"cargo") debug configuration:

{
    "type": "lldb",
    "request": "launch",
    "name": "Debug executable 'hello'",
    "program": "${workspaceFolder}/target/debug/hello",
    "args": [],
    "cwd": "${workspaceFolder}"
}

Note: I can confirm that there is indeed an executable in the program path. I'll add a preLaunchTask to automatically build later.

I'm getting the error process exited with status -1 (debugserver died with signal SIGTRAP).
I've seen multiple issues such as #414 which was marked as a duplicate of #397. Everyone else seems to be running the debugger fine on M1. Might it be because I am on a beta version of the operating system? Thank you.

Yeah, something's broken on osx 12.0. Please see this thread: #456.

[QuietRocket]

Just to update, I did the proposed fix mentioned in the thread: "delete debugserver executable in the /lldb/bin folder".

It worked like a charm. Thanks! I don't know if this issue should be kept open or a separate issue should track stable Monterey support (since I titled this one specifically 12.0 beta).

[fi6]

Installed osx 12.0, same error for me(delete still works).

[DongqiShen]

fantastic! That works for me!

[vadimcn]

I don't own an M1 mac, so would appreciate if someone could test this build for me: https://github.com/vadimcn/vscode-lldb/releases/download/v1.6.9-dev.2110291651/codelldb-bootstrap.vsix

[sh-cho]

@vadimcn It's working now with that 👍

[nelsonjchen]

@vadimcn That build works for me as well. macOS Monterey 12.0.1 on a MacBook with M1 Pro.

I tried that version and also the one from the extension marketplace (1.6.10) and launching the debugger is crashing.

@iAbadia: Same thing here. macOS Monterey on M1X. It worked perfectly fine for a few weeks and then I got that SIGSEV. Removing the binaries in extension/bin as mentioned in #456 did not work. However, running the command "LLDB: Use Alternative Backend" and inputting /usr/bin/lldb seems to do the trick for me. I guess something updated in vscode and broke things?

[iAbadia]

Thank you @johanostensson ! That worked for me too
