Here's the reduced failing testcase:

typedef __g77_integer flag;
typedef __g77_integer ftnint;

typedef struct
{ flag icierr;
        char *iciunit;
        ftnint icirlen;
        ftnint icirnum;
} icilist;

extern char *f__icptr;
char *f__icend;

void
c_si (icilist * a)
{
  f__icend = f__icptr + a->icirlen * a->icirnum;
