Segmentation fault without rip even getting overwritten Buffer Overflow

Gdb output

I was trying to overflow the return pointer of a simple program. I have asrl disabled and I compiled like this gcc returnexp.c -o returnexp -fno-stack-protector.

(I would disable noexecstack later on when I could overwrite the pointer) But everytime I overwrite the pointer, I get this error and it's not even loading the Charakters into rip so I cannot calculate the offset, nor even return to my stackframe. What can I do?
