No.  It's gone now ;)

But the FAILs remain.

I don't think this is a P1 though, lto is known to have lots of issues with
debug info, that isn't going to be fully fixed for 4.6, and this is just one of
them.

Ok, the dg-skip if works.  LTO makes us print 24 for the first i.  Because
gdb name lookup is confused if the local i is gone.

So it's really wrong debug info.  But it's hardly a regression for LTO.

I'll commit the dg-skip and leave the bug open as non-regression.

Seems to be a bug in free_lang_data_in_block, which throws away the
DECL_EXTERNAL decl from BLOCK_VARS, eventhough it is obviously very much
needed. In fact, is there ever a case where what free_lang_data_in_block does
is desirable?
