This is very puzzling.. from where the result_decl_comes from?
Can you please check the p1 and p2 in eq_node?
It seems to be that DECL_ASSEMBLER_NAME must have been executed for both
of them already when they were inserted into the table, so I really
don't understand why they are checked again...

Thanks,
