Describe the bug

I have a project that uses UniFFI and uniffi-bindgen-go to generate Go bindings for a Rust library. It appears that any unit tests that import these bindings cause the debugger not to start. Instead, it shows this error:

Failed to launch: could not launch process: could not read debug info (decoding dwarf section info at offset 0x0: too short) and could not read go symbol table (could not find rodata struct member)

Unfortunately, I don't have a simple example Rust/Go library that I can share; if that would help, I can try to put together a minimal example some time in the next few weeks.

I have built and linked the Rust bindings in both debug and release mode, but this does not seem to make a difference, and I also don't need the debugger to work across the FFI boundary, so I wouldn't expect the Rust debug symbols to matter.

This is the CGO link declaration (bindings is the name of the Rust library):

// #cgo LDFLAGS: -L../target/debug -lbindings -ldl -lm -lpthread

Using dlv test on the command line seems to work fine:

dlv test --build-flags="-tags=unit" ./queue/policy/ -- -test.run <testname>

Steps to reproduce the behavior:

I see this no matter how I launch the debugger (i.e. from the "Run and Debug" panel, from the test UI, or using the "Go: Debug Test At Cursor" command).

We recently saw a similar issue #3547 and go-delve/delve#1138.
Can you upgrade to go1.23.1 and reinstall dlv to see if it resolves your issue?
Thanks!

[BatmanAoD]

@hyangah Thank you; that worked! (It took a few tries because apparently the ~/sdk/.../go version of Go was separate from everything on my PATH, so I have no idea why VSCode was using that or how it got there. 🤨)

Sorry for opening a duplicate; #3547 is almost certainly the same issue. I looked for issues with cgo but somehow didn't find that one.
