GDB crashes when attempting to connect to a remote session while in `layout split`. If I connect to the remote session first it works, however if I already changed my view I get a core dump.

My steps to reproduce crash:
 - Run iso using `qemu-system-i386 -cdrom MyIso.iso -gdb tcp::26000 -S -monitor stdio`
 - open gdb in seperate tab
 - run `layout split`
 - run `target remote localhost:26000`
 - Crash

I was previously able to do this without crash using:
