This has one frame from C code, the actual function that crashes, crash_now.
Compared to GDB, this is not the full stack, there are some frames missing:

Tested with go version go1.19.4 linux/arm64 on Ubuntu 22.04.1 LTS (Jammy Jellyfish)
$ docker build . -t cgosymbolizertest
$ docker run --rm cgosymbolizertest
On linux arm64 I see no difference in the output.
