You're right.
It compiled with a warning:
../../gcc/ggc-common.cc: In function 'void*
ggc_internal_cleared_alloc_no_dtor(size_t, void (*)(void*), size_t, size_t)':
../../gcc/ggc-common.cc:154:44: warning: unused parameter 'size'
[-Wunused-parameter]
154 | ggc_internal_cleared_alloc_no_dtor (size_t size, void (*f)(void *),
| ~~~~~~~^~~~
and obviously didn't work right (always allocated 0-sized objects).
Fixed thusly, tested on x86_64-linux with HAVE_ATTRIBUTE_ALIAS manually
commented out in auto-host.h, committed to trunk as obvious.
Sorry.
