G++ dies instead of reporting a clear error message. This is a
regression as compared to 3.3
I'm afraid I can't currently upgrade to 4.1, so I can't tell if this
is still a problem...
Environment:
System: Linux nostromo 2.4.27-1-686 #1 Wed Dec 1 19:57:47 JST 2004 i686 GNU/Linux
Architecture: i686
host: i486-pc-linux-gnu
build: i486-pc-linux-gnu

}
EOF
: ------------------------------------------------------------
