When the compilation option is set to -DCMAKE_BUILD_TYPE=RelWithDebInfo, it appears to have some issues.

When the compilation option is set to -DCMAKE_BUILD_TYPE=RelWithDebInfo, cpptrace cannot collect specific stack information, but gdb can. However, when set to -DCMAKE_BUILD_TYPE=DEBUG, both cpptrace and gdb can collect the stack information. Why is this the case?

cpptrace tag : 0.7.1
compilation option
cmake-args:
- -DCMAKE_BUILD_TYPE=Release
- -DCPPTRACE_BUILD_SHARED=ON
- -DCPPTRACE_GET_SYMBOLS_WITH_LIBDWARF=ON
- -DCPPTRACE_UNWIND_WITH_UNWIND=ON
- -DCPPTRACE_DEMANGLE_WITH_CXXABI=ON
- -DCPPTRACE_USE_EXTERNAL_ZSTD=ON
- -DCPPTRACE_USE_EXTERNAL_LIBDWARF=ON

Hi,
I threw a quick test together locally but I see traces produced as expected -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCPPTRACE_BUILD_SHARED=ON -DCPPTRACE_UNWIND_WITH_UNWIND=ON -DCPPTRACE_DEMANGLE_WITH_CXXABI=ON:

Could you provide some more information?

I see in your followup comment you mentioned

-DCMAKE_BUILD_TYPE=Release

It's not unexpected that a stack trace would be empty under -DCMAKE_BUILD_TYPE=Release as debug symbols aren't included by default under Release.

[Eternity1987]

The option -DCMAKE_BUILD_TYPE=Release is used to compile the cpptrace dynamic library, while the executable is linked with cpptrace using -DCMAKE_BUILD_TYPE=RelWithDebInfo.

Thanks for clarifying. Is there any additional information you can provide to help me reproduce?

What platform are you on? What output are you seeing? What version of libdwarf are you using?

I'm closing for now since I have been unable to reproduce. Please feel free to re-open if there's additional info or anything that could help with reproduction. If you run into any more issues please let me know.
