Don't use "run", "run" is to start the program. Here we want to do a
post-mortem analysis of the crash using the core file. Google "gdb core
file" to have more details about what a core file is.

Can you run the gdb command, and copy/paste what you see? Without
entering any command *inside* gdb, it should already tell you which
instruction has faulted, and for what reason.

It could. But at least gdb will tell us if it's an undefined
instruction, an invalid memory access, an unaligned access, or
something else.

Right left to the "Paste" button there is a little box to train your
mental calculation. You should pay attention to it :-)

Thanks,
