Please note the warning under @option{-fgcse} about

invoking @option{-O2} on programs that use computed gotos.

|

+NOTE: In Gentoo, @option{-D_FORTIFY_SOURCE=2} is set by default, and is
|
|
+activated when @option{-O} is set to 2 or higher. This enables additional

|
+compile-time and run-time checks for several libc functions. To disable,
|
|
+specify either @option{-U_FORTIFY_SOURCE} or @option{-D_FORTIFY_SOURCE=0}.
