Compiling the following (on Fedora 7 x86_64) with "-Wall -O3" gives
d.c:11: warning: ?r.c? is used uninitialized in this function
and as it says, doesn't initialize the .c member though it should.
#include <stdio.h>
#include <pthread.h>
int main(int c, char **v)
{
int j[3];
struct { int c, *j; pthread_mutex_t m; } r = {
.j = j, .m = PTHREAD_MUTEX_INITIALIZER,
};
printf("current should be zero but is %d\n", r.c);
return 0;
}
$ gcc -v
Using built-in specs.
