You still have not provided an executable. WebKit is a library, but it
doesn't execute "on its own". It is loaded into *some* executable;
namely the one that is running in process <PID>. If you don't know
which executable that is, try "ps -fp <PID>".

Why not? Once you figure out which executable is running "inside"
process <PID>, invoke GDB like this: "gdb -p <PID>
/path/to/executable", and you should be good to go (assuming you don't
run out of memory that is -- AFAIU WebKit is very large, and I believe
you are quite unlikely to succeed with "native android GDB").
