That is the result of line 24 right here in `[ests/c_unittests/CMakeLists.txt`. What I find strange is that the _FORTIFY_SOURCE is actually not undefined by this. Maybe the `-Wp,` has some strange powers? > In any case, does any of the upstream CI builds use the `-D_FORTIFY_SOURCE`? Ubuntu in Travis CI, because Ubuntu enables _FORTIFY_SOURCE with -O1 or higher by default, at least according to https://stackoverflow.com/questions/34907503/gcc-fread-chk-warn-warning. -- This is an automated message from the Apache Git Service.
