FYI, when we picked up r194286 into google/gcc-4_7 branch, and ran our 500,000
validation tests, we discovered two instances of mis-compilation.
This code:
typedef vector<void*> T[13];
void foo() {
T x;
...
}
is mis-compiled to omit 13 calls to vector::vector, and x[0], x[1], etc. all
contain uninitialized stack garbage data members.
I've confirmed that trunk compiler is similarly broken.
Unfortunately I haven't been able to reduce the test case that exposes the
problem yet.
