I wanna debug an AVR program with avr-gdb while using simulavr as the simulator, as long as I'm not using ddd, things work, but once I use ddd for some graphical interface, as I'm new to gdb, the simulavr crashes. Here is what happens:
$ simulavr -d atmega8 -f main.elf -g
Waiting on port 1212 for gdb client to connect...
$ ddd --debugger "avr-gdb main.elf"
in the gdb command line inside ddd:
(gdb) target remote localhost:1212
warning: Can not parse XML target description; XML support was disabled at compile time
0x00000000 in __vectors ()
(gdb) load

(gdb) step
Single stepping until exit from function __vectors,
which has no line number information.
0x00000026 in __trampolines_start ()
(gdb)
as soon as I step, simulavr crashes like this:
