Unable to resovle / verify breakpoints on Windows / C++

[eranif]

OS: Windows 10
VSCode version: N/A
CodeLLDB version: Latest 1.7
Compiler: clang using MSYS (from the clang64 repo)
Debuggee: C++

CodeLLDB is unable to resolve breakpoints
I have a simple 1 file test program compiled with debugging symbols using clang++ on Windows.

codelldb is unable to resolve breakpoints, unless its a function breakpoint
the same code, using lldb-vscode works as expected.

CodeLLDB:

[19:58:39:331 DEBUG] --> {"seq":14,"type":"request","command":"setBreakpoints","arguments":{"source":{"name":"main.cpp","path":"C:\\Users\\eran\\Downloads\\testclangd\\main.cpp"},"breakpoints":[{"line":41,"condition":""},{"line":43,"condition":""}]}}
[19:58:39:335 DEBUG] <-- {"seq":34,"type":"response","request_seq":14,"success":true,"command":"setBreakpoints","body":{"breakpoints":[{"id":2,"message":"Resolved locations: 0","verified":false},{"id":3,"message":"Resolved locations: 0","verified":false}]}}

lldb-vscode:

[20:00:35:792 DEBUG] --> {"seq":18,"type":"request","command":"setBreakpoints","arguments":{"source":{"name":"main.cpp","path":"/Users/eran/Downloads/testclangd/main.cpp"},"breakpoints":[{"line":45,"condition":""}]}}
[20:00:35:794 DEBUG] <-- {"body":{"breakpoints":[{"id":4,"line":45,"source":{"name":"main.cpp","path":"/Users/eran/Downloads/testclangd/main.cpp"},"verified":true}]},"command":"setBreakpoints","request_seq":18,"seq":0,"success":true,"type":"response"}

this seems like something trivial and I must be missing something here
any hint is appreciated

Thanks

One thing that stands out is that in the first case file paths use Windows notation (drive letter and backslashes), while in the second it's Unix notation. Which notation is used in the debug info? If they are mismatched, lldb may be unable to match path in the breakpoint set request to that in the debug info.

I tried all the variations (forgot to mention this):

• main.cpp
• C:\Users\eran\Downloads\testclangd\main.cpp
• C:/Users/eran/Downloads/testclangd/main.cpp
• /Users/eran/Downloads/testclangd/main.cpp

[22:44:57:513 DEBUG] --> {"seq":18,"type":"request","command":"setBreakpoints","arguments":{"source":{"name":"main.cpp","path":"main.cpp"},"breakpoints":[{"line":43,"condition":""}]}}

lldb-vscode accepts and verifies both: main.cpp and /Users/eran/Downloads/testclangd/main.cpp
while codelldb is not able to verify any of the cases I tried

same executable is used in both debuggers, different results
