llvm-symbolizer doesn't work for apt.llvm.org releases #109282

Open bgemmill opened 2 weeks ago

@sylvestre requested this be made into it's own issue.

While investigating 109037, stack traces from the apt.llvm.org release of clangd only show binary addresses even when llvm-symbolizer is installed and on the path, like this:

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.

Signalled during AST worker action: Update

@vient mentioned this was because the binaries there are stripped, and it doesn't look like the repository has a set of -dbg packages to install to provide symbols.

Could llvm-symbolizer be made to work with the binaries provided from apt.llvm.org in some way?
