Hello,
I am delighted you found contributing to GCC interesting. Sorry for the
delay in replying.
I am adding the GCC mailing list in case other GCC developers have
something to add to my reply. It is usually a good idea to email the
list and not an individual, if only because most of the commu
The following can be a possible example of a case where the analyzer fails
to understand POSIX file-descriptor API.

#include
#include
void test()
{

fd = open("foo.txt", O_RDONLY | O_CREAT);

void test_2()

The %m format specifier is a documented feature of syslog, but gcc gives a

For example, the program:
#include
int main(void)
{
syslog(LOG_ERR, "%m");
return 0;
}
gives:
warning: ISO C does not support the ‘%m’ gnu_printf format [-Wformat=]
