    	Hi,
    	Solaris 7 on sparc 64bits crashes but you need to fill the
    buffer with more than 1200 bytes.
    	The segfault occurs on a ldsb instruction, so I don't know if
    its feasible to exploit this bug (Haven't done enough investigation).
    	Knowdays I'm using wrappers to prevent this kind of exploits
    since I can't afford to wait for Sun's patches. If you need a quick
    workaround using wrappers drop me a mail and I'll send you a simple
    wrapper.
