CryZe opened issue #7720:

Attaching to wasmtime with LLDB stopped working after switching to wasmtime 16. It still worked perfectly fine on wasmtime 15.0.1. These are all the changes (i.e. only version bumps):

I don't see anything in the changelog indicating that something changed regarding the DWARF support.

Do you perhaps depend on Wasmtime with default-features = false? If that's the case the support for this was moved behind a debug-builtins feature which will need to be enabled.

CryZe commented on issue #7720:

Yeah that seems to fix it. However it seems like that this is not documented at all:

  1. The changelog doesn't mention it.
  2. The crate features section doesn't mention it: https://docs.rs/wasmtime/16.0.0/wasmtime/index.html#crate-features
  3. The debug_info function on the Config isn't feature gated by it, nor mentions it: https://docs.rs/wasmtime/16.0.0/wasmtime/struct.Config.html#method.debug_info

Good point! I've pushed https://github.com/bytecodealliance/wasmtime/pull/7736 to add some docs.
