Test case
The following program:
extern "C" int printf(const char *, ...);
struct Foo {
Foo(int x) { printf("INIT: %d\n", x); }
};
Foo f(1);
Foo f2(2);
Foo f3(3);
__attribute__((init_priority(101)))
Foo g0(101);
__attribute__((init_priority(65534)))
Foo g(65534);
__attribute__((init_priority(65535)))
Foo h(65535);
int main(void) {
return 0;
}
- when compiled with clang++ (5.0.0) displays:
INIT: 101
INIT: 65534
INIT: 65535
INIT: 1
INIT: 2
INIT: 3
- when compiled with g++ (5.4.0) displays:
INIT: 101
INIT: 65534
INIT: 1
INIT: 2
INIT: 3
INIT: 65535
g++ seems to consider that init_priority 655535 happens after standard dynamic
initialization.</pre>
