Bug#708164: nginx proxy_pass buffer overflow (CVE-2013-2070)

[steven hay]

I understand if this patch may not be 100% correct, but if I read the 
references correctly, the error is more of theoretical than practical concern 
since this particular compiler optimization is not likely to be implemented in 
the GNU compiler. Do we really think that GNU would include an optimization 
that broke 95% of the bounds checking implementations existing in the wild?
