Invalid thread local object initialization.
Snippet:
#include <iostream>
using namespace std;
struct far {
struct boo {
boo () {
cerr << "bar::boo" << endl;
}
int i = 42;
};
static void baz() {
cerr << far::FOO.i << endl;
}
static thread_local boo FOO;
};
thread_local typename far::boo far::FOO;
int main() {
far f;
cerr << f.FOO.i << endl;
cerr << far::FOO.i << endl;
return 0;
}
Output:

Template class' thread_local member is not initialized unless other
non-template class' thread_local member is initialized first:
#include <iostream>
using namespace std;
struct far {
struct boo {
boo () {
cerr << "far::boo" << endl;
}
int i = 42;
};
static void baz() {
cerr << far::FOO.i << endl;
}
static thread_local boo FOO;
};
template<class T>
struct bar {
struct foo {
foo () {
cerr << "bar::foo" << endl;
}
int i = 42;
};
void baz() {
cerr << bar::FOO.i << endl;
}
static thread_local foo FOO;
};
template<class T> thread_local typename bar<T>::foo bar<T>::FOO;
thread_local typename far::boo far::FOO;
int main() {
bar<int> b;
b.baz();
far f;
f.baz();
return 0;
}
Output:
0
far::boo
bar::foo
42

Smaller testcase that reproduces the problem
clang had the same problem, this smaller test was submitted to the clang team
and they identified it as a duplicate of a recently fixed bug:
http://llvm.org/bugs/show_bug.cgi?id=19254
Which was fixed as follows
http://llvm.org/viewvc/llvm-project?view=revision&revision=204869
With the following comment:
PR19254: If a thread_local data member of a class is accessed via member access
syntax, don't forget to run its initializer.
