Self clarification:       GCC does have an option to enable stack canaries, but it is opt-in       rather than enabled by default (say, in MSVC one would need to opt-out       instead).              What I wrote could be misinterpreted, I meant GCC's default settings do       little in the case of protecting against stack overflows (and was *not*       implying that canaries were ineffective).              But, alas, now people will probably be misinterpreting what I wrote and       now I will need to deal with this, grr...              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
