Invalid symbols and missing location for DWARF files when using samply-symbols crate

Hello, I encountered the following problem when using [samply-symbols](https://github.com/mstange/samply/tree/main/samply-symbols): for a binary compiled for Linux, it is not possible to obtain normal symbols and location, file name and line number. Moreover, everything is in the file itself. I made a small [MVP](https://github.com/bugrazoid/symbolic-fail/tree/master) for Linux, which shows that there are both symbols for the function and data on its location. This is what I get for the `lib_fn` function from my MVP: ``` [app/src/main.rs:66:9] &symbol = AddressInfo { symbol: SymbolInfo { address: 43312, size: Some( 50, ), name: "lib_fn\0_Unwind_Resume@@GCC_3.0\0__cxa_finalize@@GLIBC_2.2.5\0_Unwind_SetIP@@GCC_3.0\0", }, frames: None, } ``` It can be seen that `symbol.name` contains the desired name, but there are also extra symbols. And for some reason there are no frames in which, in PDB and Mach-o, both the normal function names and their locations were located. If you inspect the file itself, you can see that there is a function name there: ``` $ readelf -s -W liblib.so | grep lib_fn 51: 000000000000a930 50 FUNC GLOBAL DEFAULT 11 lib_fn 795: 000000000000a930 50 FUNC GLOBAL DEFAULT 11 lib_fn ``` and data about the file and line: ``` $ readelf --debug-dump=decodedline liblib.so | head -n11 Contents of the .debug_line section: CU: lib/src/lib.rs: File name Line number Starting address View lib.rs 2 0xa930 lib.rs 3 0xa934 lib.rs 2 0xa947 lib.rs 3 0xa94d lib.rs 4 0xa95d lib.rs 4 0xa962 ``` Please tell me, maybe I'm doing something wrong? Or is there some other problem?
