--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Hmm, it seems we triggered another bug of aliases WRT anchors. How does the
declarations in question look like? (basically all aliases introduced by
ipa-icf can also be coded by hand).
Is it the path
/* For a duplicate declaration, we can be called twice on the
same DECL node. Don't discard the RTL already made. */
if (DECL_RTL_SET_P (decl))
...?
Why the declaration is considered duplicate to start with?
