System: NetBSD bonnet.wsrcc.com 2.0B NetBSD 2.0B (WSRCC) #5: Fri Apr 2 12:59:48 PST 2004 wolfgang@bonnet.wsrcc.com:/var/obj/netbsd/sys/arch/amd64/compile/WSRCC amd64

>Description:

    x11-ssh-askpass SEGV's in a way that appears to trash the stack.

    When it is recompiled with just "-g" it runs fine.  It is not
    clear if this is a gcc problem or simply bad code in the
    application or libraries.
	
>How-To-Repeat:

    with default build (CFLAGS=-O2) out of pkgsrc/security

    $ gdb x11-ssh-askpass
    ...
    (gdb) run
