------- Comment #1 from pinskia at gcc dot gnu dot org 2005-10-07 19:27 -------
Confirmed, this was always broken in that we got wrong code in 4.0.0 but now we
get an ICE which means this is a regression and a progression.
Adding -W -Wall for 4.0, you get a warning:
t.c: In function ?test?:
t.c:9: warning: ?({anonymous})? is used uninitialized in this function
