Got another one:

struct a {
  struct b

$ clang_delta --transformation=empty-struct-to-int --counter=1 input.c
Segmentation fault

BTW, I think a "meta-bug" is that the creduce_bug_* directories are
numbered 001 to 009 but after that it doesn't create e.g. 010 onwards
despite the fact that there are more crashes.
