--- Comment #34 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
from ggc.h:
```
/* The internal primitive.  */
extern void *ggc_internal_alloc (size_t, void (*)(void *), size_t,
                                 size_t CXX_MEM_STAT_INFO)
     ATTRIBUTE_MALLOC;


...

/* Allocates cleared memory.  */
extern void *ggc_internal_cleared_alloc (size_t, void (*)(void *),
                                         size_t, size_t
                                         CXX_MEM_STAT_INFO) ATTRIBUTE_MALLOC;
```

I am not 100% sure that is valid with LTO especially if ggc_free can be
inlined.

a simple test is to mark ggc_free as noinline (or noipa) or remove the
ATTRIBUTE_MALLOC usage from ggc.h header file.
