Why did it stop after 3 frames?  These frames don't tell anything
useful about the crash.  Can you supply more?

That's because you didn't start GDB from the src directory.
xbacktrace is a command defined in src/.gdbinit, so you need to invoke
GDB from that directory in order to be able to use that command.
