The extension "init_priority" doesn't work correctly on some platforms. Global
static objects are not deinitialized in a proper order, as the following
testcase shows. It is probably because of a linker bug.
----------------------------8<------------------------------
#include <stdio.h>
struct A {
A() {
printf("A()\n");
}
~A() {
printf("~A()\n");
}
};
struct B {
B() {
printf("B()\n");
}
~B() {
printf("~B()\n");
}
};
struct C {
C() {
printf("C()\n");
}
~C() {
printf("~C()\n");
}
};
struct D {
D() {
printf("D()\n");
}
~D() {
printf("~D()\n");
}
};
static A a;
static B b;
static C c __attribute__((init_priority(101)));
static D d;
int main(int argc, char *argv[])
{
return 0;
}
----------------------------8<------------------------------
It produces:
C() <= this is OK because of init_priority
A()
B()
D()
~C() <= deinitialization order error
~D()
~B()
~A()
But it should be:
C()
A()
B()
D()
~D()
~B()
~A()
~C() <= should be deinitialized here
