<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri","sans-serif"">> So I think -fstack-protector is what I need to use, but I can't find any Clang documentation about it. Any suggestions?

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Calibri","sans-serif"">Experimenting with clang -v and the various -stack-protector options reveals that Clang as far back LLVM3.1 has used -fstack-protector by default, and has -fstack-protector-all.
Clang from LLVM 3.7 implements -fstack-protector-strong, which seems like the sensible thing to try as an upgrade from the basic -fstack-protector.
