Xcode's lldb-rpc-server crashing on macOS 13.3

[khronokernel]

Currently the exact cause is unknown, however @ASentientBot believes the issue is likely due to LLDB trying to parse binaries extracted from the dyld shared cache with DSCE.

Originally reported by NSGod, they've provided a sample project to replicate the issue:

• lldb-rpc-server sample project

One project is built and ran, you should see an lldb-rpc-server crash in ~/Library/Logs/DiagnosticReports such as this one:

• lldb-rpc-server-2023-03-29-192320.ips.txt

Notes:

• AMFI has been verified to not be the cause
• With 13.3, GPUSupport.framework's 31001 binaries needed downgrading to 13.2.1's. Most likely these binaries are the ones at fault
• Disabling Debug executable can work-around the crash (reference)

Due to the implications with DSCE and our lack of on-disk binaries, we cannot comment if this issue can be resolved in a reasonable time. Recommend downgrading your OS if this is critical to your workflow.

this is confirmed "fixed" with dsce pad argument which produces multiple GB binaries; however that is obviously not a shippable solution. unsure if another fix is possible
