Description

When attempting to generate code for a Thrift file like:

struct X {
  required string my_field;
}

const X CONSTANT_X = {
  'my_field_1' : 'blah'
}

I find that I get a segfault. GDB tracks it back to line 99 of t_scope.h, where it looks like we try to get a t_field object from the parent struct by name, and then ultimately don't check if we actually got back something valid or not.
