It doesn't do it... tried that first ;-) [ and it is copied] However, I see the comment that variables can change status during their life - or perhaps it's a bug... I also tried TREE_ADDRESSABLE and DECL_PRESERVED_P - but now I see that these are not copied. hmmm -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43553
