--- Comment #36 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I am having problem to reproduce it on a cross compiler.  I assume you have
non-plugin-enable LD setup, right?

There is problem with chained weakrefs that ought to be fixed by the following
change:

+             : DECL_ASSEMBLER_NAME (symtab_alias_ultimate_target

       }
 #endif


I however do not see any chained weakrefs in the preprocessed file attached, so
I am not quite convinced this can change anything.

Can you, please, run it in debugger and take a look what is the assembler name
ultimate_target is called for and what is its CHAIN_DECL?
