The test is new, how could this be a regression?
Yes, -flto/-fwhopr has lots of issues with debug info.

------- Comment #4 from rguenth at gcc dot gnu dot org 2010-09-02 11:08 -------
I can't get anything but { dg-skip-if "" { *-*-* } { "-fwhopr" "-flto" } { "" }
} to work. But then -O0 still fails for me.
13 int i = 42;^M
$1 = 0^M
$2 = 42^M
0 != 42
with gdb 7.1.

This isn't a testsuite bug, but lto/whopr bug, and IMHO quite severe, it
affects debugging even at -O0.

------- Comment #6 from jakub at gcc dot gnu dot org 2010-09-02 12:37 -------
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?
