Slightly reduced test-case:

$ cat x.c
typedef struct {
} REFERENCE;
#define LIM2() LIM1()
#define LIM3() LIM2() LIM2() LIM2() LIM2() LIM2() LIM2()
#define LIM4()                                                                
\
  LIM3() LIM3() LIM3() LIM3() LIM3() LIM3() LIM3() LIM3() LIM3() LIM3()
#define LIM5()                                                                
\
  LIM4() LIM4() LIM4() LIM4() LIM4() LIM4() LIM4() LIM4() LIM4() LIM4()
#define LIM1() DEF(),
REFERENCE references[] = {LIM5()}
