I am getting this crash on the new Android N preview emulator, right on the start.
qemu: fatal: goldfish_tty_read: Bad offset 20 RAX=0000000000000009 RBX=0000000
I had the same issue today. Managed to fix it by changing emulator's ABI from x86_64 to x86. Create new Virtual Device and on System Images list select the image with x86 ABI (Download it if you don't have it already). Hope it helps.
