GCC does not warn for this:
int main()
{
wprintf (L"%s", 5);
}
GCC should try converting the string to single-byte (e.g. to UTF-8, which would
work for any wchar_t encoding in which 0-127 maps to char's encoding) and test
the format string.

But it should still have appropriate accessors for extracting bytes / multibyte characters / wide characters from strings (such that support for non-8-bit target bytes could be added to those accessors later), though without necessarily finding all existing code that should be using those accessors. See also bug 20110 on the format checking not allowing for the execution character set once it's extracted a character from the string. For wide characters it's -fwide-exec-charset that's relevant. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38308 ^ permalink raw reply [flat|nested] 5+ messages in thread
