[posixtest-discuss] Compiling testcases with _FORTIFY_SOURCE=2

[Patrick K. <pk...@su...>]

Hey,

Can you add the parameter "-D_FORTIFY_SOURCE=2" as a standard for
compiling posix-testcases?

FORTIFY_SOURCE is a Glibc feature which adds memory and string function
protection. There is no home site for this feature, but it is described
well on this page: http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html

With FORTIFY_SOURCE option compiling, I saw a lot testcases segfaulting,
due to too short char array, see attached patch (they all have the same
problem, the former char array size of 20 iss too short, if the PID is
randomly too large).
