Do you use native gdb on ARM ?

What I saw for m68k is it cannot access to the saved registers of the core dump (i.e. you cannot use cross-compiled gdb to debug a core dump ...) What you can try is to generate a core dump with a "kill -SIGILL" on a qemu-arm process (don't forget to do "ulimit -c unlimited" before) and then load the core with your cross-compiled gdb.
