<pre>This test case passes on Linux but fails on Windows, with -O0. When compiled
with the Microsoft compiler, the test case passes.
Output: Fail hist is 0 4
$ cat bug.cpp
#include <stdio.h>
long hist_ = 0;
template <class T>
struct X_ {
static T i;
static T init() { hist_ |= sizeof(T); return T(); }
};
template <class T> T X_<T>::i = X_<T>::init();
template struct X_<int>;
int main(int argc, char *argv[])
{
X_<int> my_var2;
if (hist_ != sizeof(int)) {
printf("Fail hist is %d %d\n", hist_, sizeof(int));
// On Windows, this exit is taken
return 4;
} else
printf("Pass hist is %d %d\n", hist_, sizeof(int));
return 0;
