Here is an example to repro the bug:
$ cat a.cpp
#include <cstdio>
struct test {
test() {
printf("i am constructed!\n");
}
};
test test1;
__attribute__((constructor(0))) void cons_highestpri() {
printf("i am also constructed highest pri!\n");
}
__attribute__((constructor(1010))) void cons_lopri() {
printf("i am also constructed lopri!\n");
}
test test2;
int main() {
}
$ cat b.cpp
#include<cstdio>
__attribute__((constructor(101))) void cons_hipri() {
printf("i am also constructed hipri!\n");
}
$ clang++ -flto=thin a.cpp b.cpp -O2 && ./a.out
i am also constructed highest pri!
i am also constructed lopri!
i am constructed!
i am constructed!
i am also constructed hipri!</pre>
