Depends on how the language runtime defines its calling convention, does it follow System Linkage [1] or does it implement its own internal linkage ie Private Linkage? If it follows standard System Linkage, its easy to point gdb or any other system debugger or profiler to debug and profile the application. Some runtimes have a mix of System and Private linkage, ie C functions will follow System Linkage but JIT'ed code frames might follow private linkage. This makes for difficult stack-walking by system native debuggers and profilers. You'd have to teach GDB via an extension how to walk the non-standard frames. So yea, long story short, it depends on the linkage convention the implementers of the language runtime decided to follow.
