The following testcase is miscompiled:

#include <stdio.h>
double foo() { return 1.0; }
static struct S { S(); } s;
static const double Y = foo()+2.0;

S::S() {
  printf("%f\n", Y);
}
int main() {
  printf("%f\n", Y);
}

Both printfs should print 3 based on Mark's insight in Comment #22 of bug
21089.

-Chris

Note that this could be handled in a straight-forward way with init priorities.

Confirmed, not a regression.

Hmm, ICC gets it wrong too, maybe there is a misunderstanding somewhere.

------- Comment #4 from jason at gcc dot gnu dot org  2007-10-04 01:45 -------
This is not a bug; Mark's comment in bug 21089 had to do with the fact that
[basic.start.init] says that static initialization happens before dynamic
initialization.  Using foo() in Y's initializer makes Y dynamically
initialized, so it is not required to be initialized before s.
