Fill a GCC PR?
I am not expert in these but is it OK that it evaluates the parameter three
times?

Subject: how to fool gcc?
I'm having trouble with some uncommitted OpenPAM patches that I'd like
to get into the tree. The problem actually doesn't occur with a
normal build, but it prevents me from building a debugging version of
libpam.
Part of the patch declares openpam_log(3) as printf-like so gcc can
check format strings etc. However, openpam_log(3) is also used in
debugging macros such as this:
#define RETURNS(s) do { \
if ((s) == NULL) \
openpam_log(PAM_LOG_DEBUG, "returning NULL"); \
else \
openpam_log(PAM_LOG_DEBUG, "returning '%s'", (s)); \
return (s); \
} while (0)
