GDB internal error

[Rahul13694]

A Process during runtime is stopping and making a core file when trying to find the reason for the disruption getting this error: "internal error - unimplemented function unk_lang_create_fundamental_type called.". Any idea as to why getting such error and how to resolve it?

In general, the best place to find gdb experts is on the FSF gdb mailing list.

unk_lang_create_fundamental_type was removed in 2007 which is long before RISC-V support was added upstream. If you are using some old custom gdb port, it will be hard to get any support for it.
