Hello,
In gcc versions starting from 4.8, it seems that printf format warnings
in macros are inconsistent, depending on whether the header defining the
macro is included as a system header or not, and on the build mode (C or
C++).
With gcc < 4.8 (tried gcc 4.6.3 and 4.7.2), there are printf format
warnings for both C and C++ languages, when the macro is in a system
header or not.
With gcc >= 4.8 (tried 4.8.2 and 5.2.1 snapshot), there are no printf
format warnings when the build mode is C++ *and* when the macro is in a
system header.
If the build mode is C or if the macro is in a non-system header, the
printf format warnings are emitted.
I'm inclined to say it's a bug. I recommend opening it in Bugzilla.
Hello Martin,
Thanks for your answser and details.
I have opened a bug in bugzilla:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68052
It would probably be useful to add your comments in there.
Cheers
