opened on May 1, 2025

Create a file main.cxx with the following content and open it using clangd-enabled code editor.

template<typename T,
         int I,
         template<typename> class TT>
  class A;               // ↑ [Go to type definition] at the `class` keyword

template<typename> class X;

A<int, 0, X> * a1;

Go to type definition at the token class on the third line leads to a crash. The LSP request is

{
  "jsonrpc": "2.0",
  "id": 8,
  "method": "textDocument/typeDefinition",
  "params": {
    "textDocument": {
      "uri": "file:///tmp/export/input_120/workspace/main.cxx"
    },
    "position": {
      "line": 2,
      "character": 28
    }
  }
}

The stack trace is

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