Yes.

Likewise to here. But with recent 3.3-hammer you have to add 
-fno-unit-at-a-time since that's enabled on the branch.

Just ./contrib/gcc_update -d as of today:

[gb@hp6 gcc]$ ./xgcc -B $PWD ~/vrac/zsh-bug.c -O2 -fno-unit-at-a-time
[gb@hp6 gcc]$ ./a.out
Aborted

GNU C version 3.3.1-hammer 20030703 (prerelease) (i686-pc-linux-gnu)
actually refered to co from 20030708, according to ChangeLog.hammer.
