GDB can't find the unwind table
GDB needs some help to understand Loko's stack frames. The code that helps it is in arch/amd64/loko-gdb.py
.
For unknown reasons the call gdb.lookup_global_symbol('bootstrap_unwind_table')
is not working, GDB doesn't find the symbol. So the location of the unwind table is hard coded, which easily breaks.
Either fix LokoUnwinder
to do the right thing, whatever that is, or work around it by putting the address of the unwinding table at a known location.
