Getting "Source not available, cannot jump to frame" when using C with lldb-dap on Mac M1 about nvim-dap

[mfussenegger]

The stacktraces reported by the debug adapter have no sources:

    stackFrames = { {
        column = 0,
        id = 524288,
        instructionPointerReference = "0x100E7E4C8",
        line = 0,
        name = "__sanitizer::SizeClassAllocator32<__asan::AP32<__sanitizer::LocalAddressSpaceView>>::PopulateFreeList(__sanitizer::AllocatorStats*, __sanitizer::SizeClassAllocator32LocalCache<__sanitizer::SizeClassAllocator32<__asan::AP32<__sanitizer::LocalAddressSpaceView>>>*, __sanitizer::SizeClassAllocator32<__asan::AP32<__sanitizer::LocalAddressSpaceView>>::SizeClassInfo*, unsigned long)",
        presentationHint = "subtle"
      }, {

Not much the client can do about that.
Given that you didn't' post any sources I also can't reproduce this.

@mfussenegger sorry about that, my mistake. Here's small repo for you to use: https://github.com/benjitrosch/c-dap-example/tree/main

The example works fine for me - tested with all 3: lldb-vscode (version 17.0.6) , codelldb and gdb.

stackFrames from lldb-vscode look like this for me:

  body = {
    stackFrames = { {
        column = 3,
        id = 524288,
        line = 13,
        name = "main",
        source = {
          name = "main.c",
          path = "/path/to/benjitrosch/c-dap-example/main.c"
        }
      }, {
        column = 0,
        id = 524289,
        line = 27,
        name = "___lldb_unnamed_symbol3264",
        source = {
          name = "___lldb_unnamed_symbol3264",
          sourceReference = 1
        }
      }, {

Thanks for trying it out. Really weird that it's not working for me.

I'm using lldb-dap which gets installed from brew install llvm which is at version 18.1.4. I tried downgrading with brew install llvm@17 but then neither lldb-dap nor lldb-vscode were anywhere to be found.

Not sure what other info I could provide, please LMK.
