GCC 8.0+ <https://gcc.gnu.org/gcc-8/changes.html> introduces a new warning about unsafe macros expanding to multiple statements used as a body of a statement such as if, else, while, switch, or for. In combination with -Werror this can cause the compilation to fail: |In file included from xmalloc.c:37: |xmalloc.c: In function 'xmalloc': |system.h:39:2: error: macro expands to multiple statements [-Werror=multistatement-macros] | fflush(stdout); \ | ^~~~~~ |xmalloc.c:52:5: note: in expansion of macro 'error' | error (EXIT_FAILURE, 0, _("memory exhausted")); | ^~~~~ |xmalloc.c:51:3: note: some parts of macro expansion are not guarded by this 'if' clause | if (p == NULL) | ^~ Signed-off-by: Christian Lamparter <chunkeey@gmail.com> |
