Previously, SSPBufferSize was assigned the value of the "stack-protector-buffer-size" attribute after all uses of SSPBufferSize. The effect was that the default SSPBufferSize was always used during analysis. I moved the check for the attribute before the analysis; now --param ssp-buffer-size= works correctly again.
