Segfault when compiling wrong program

[codename68]

The compiler segfaults on the following program:

struct X { field: Option<X> }

fn main() { let x = X { field: None }; }

Surprisingly, the following program successfully compiles:

struct X { field: Option<X> }

fn main(){}

Thanks for the report! I believe that this is a duplicate of #3779, however. The segfault is because of stack overflow, and both programs should indeed just get outright rejected from the compiler.
