[looks like bug #39959]

The same happens with -combine on following code (arm-none-eabi target):

a.h:

struct a {
        int b;
        int c;
};

extern struct a *p asm("r4");

void d(int *);

b.c:

#include "a.h"
void t1()
{
        d(&p->b);
}

c.c:

#include "a.h"
void t2()
{
        d(&p->c);
}

gcc -combine -c b.c c.c
b.c: In function 't1':
b.c:2:6: error: type mismatch in indirect reference
struct a

struct a

D.2762 = &p.1->b;

b.c:2:6: internal compiler error: verify_gimple failed

code 'cat' together compiles.
