Especially, it seems that there is a missing codimension/coindexed condition guarding the warning if I compare to the flag_realloc_lhs conditions in trans-expr.c I would rather move the warnings to a function and call it in the places where we really generate the extra code, like it's done for -Warray-temporaries.
