[Debugger] Breakpoints won't be hit

Bug type: Debugger

Environment
I'm using vscode in remote mode. The client is macOS and the server is Linux.

• OS and Version: Client: macOS big sur 11.5.1 (20G80), Server: Linux 3.10
• VS Code Version: Version: 1.59.1, Commit: 3866c3553be8b268c8a7f8c0482c0c0177aa8bfa
• C/C++ Extension Version: v1.6.0-insiders3

Description

I can set breakpoints in vscode UI, but when I launch a program to debug, the breakpoint is not activated and won't be hit.

I'm sure it's vscode's problem because the same breakpoint works well when I use the pure gdb command.

Since I only met this problem in my complicated huge project, and I can't reproduce it in simple projects. The only thing I can provide is the full trace log of the debugger.

In my case the breakpoint to be set is src/ray/rpc/test/grpc_server_test.cc:20, I've greped src/ray/rpc/test/grpc_server_test from the log, it is:

To Reproduce
I'm sorry but I can't reproduce it in a simple project so I can't offer an example now. If you can't address this issue via logs. Please tell me, I'll try to provide my full project to you.

Inizia con il dbg.log allegato e la richiesta setBreakpoints per src/ray/rpc/test/grpc_server_test.cc:20, quindi confronta le posizioni dei breakpoint e i percorsi dei sorgenti registrati con la configurazione remota macOS/Linux segnalata. Il lavoro è completato quando viene identificato il motivo per cui il breakpoint non è utilizzabile in questo progetto e viene verificata una correzione con lo scenario fornito.
