Hi Stuart,
Exception 14 is a page fault. Also note that I've found problems in
general with gdb-4.18 and gdbstubs with respect to offsets and file
positions not matching, switching to 4.16 fixed this for me (on
gdbstubs). This may have a similar interaction with the RTL debugger,
as that too is based on gdbstubs.
Regards, Stuart
