Can GDB debug itself? Can GDB be run on itself? How or why not?
I see something about it http://www.math.utah.edu/docs/info/gdbint_3.html
But GDB might not be written in a language that it can debug?
Yes, it's possible. Here's how to do it.


Obtain the source code for gdb.
Compile with the -g flag on.
Run gdb gdb.
