I saw that GCC 4.5 and above versions should support –D_FORTIFY_SOURCE=2 option. But it does not work for me, it has been ignred and it does not report issues when i used.
Compiler version used is "g++.c4.5.3-p0", Will it ignore the option?

In most systems,
–D_FORTIFY_SOURCE=2is only activated when also using-O2, ie, GCC compiler optimizations level 2 (or more). Try to use-O2 –D_FORTIFY_SOURCE=2to see if it works.
