Quoting spread_generic.c:
145 for (n = 0; n < ncopies; n++)
146 {
147 memcpy (dest, sptr, size);
148 dest += rdelta;
149 }
The C 99 Standard has the following to say about the mem* functions (7.21.2.1
ff):
Where an argument declared as size_t n specifies the length of the array for a
function, n can have the value zero on a call to that function. Unless
explicitly stated otherwise in the description of a particular function in this
subclause, pointer arguments on such a call shall still have valid values, as
described in 7.1.4.
So "size" can be zero, *but the the pointer arguments on such a call shall
still have valid values.*
