------------------ Additional Follow-up Comments ----------------------------
In the three lines mentioned memcpy is not used directly, but there are pass-by-value
semantics used. As a consequence it seems that newer versions of gcc try to use memcpy
(from stdlib) to create the duplicate structures.
I fixed the problem in my environment by adding the following code to the end of
stage2/char_io.c:
#undef memcpy
void *
memcpy (void *to, const void *from, int len)
{
return grub_memmove (to, from, len);
}
There are most likely more elegant ways to resolve this issue.
