Reduced testcase:
typedef struct __jmp_buf_tag { char buf[1024]; } jmp_buf[1];
extern int setjmp (jmp_buf);
extern int bar (unsigned int *);
extern jmp_buf *baz (void);
struct C { int c1; unsigned int c2, c3, c4; };
void
foo (struct C *x, const int *y, unsigned int *z, unsigned int e, unsigned int
g)
{
unsigned int d;
unsigned long f;
setjmp (*baz ());
f = d;
if ((x->c1 || x->c2) && g && (!e || d >= 8))
d = 16;
else
d = 8;
if ((!x->c3 && !x->c4 || *y == 0) && !e && bar (z))
*z = f;
}
