Can someone confirm that this
http://codepad.org/I313t7BN
compiled with
g++ -O3 test.cpp -o test
gives a segfault when trying to run it via
./test
same here:
11:14:33 [~/idownload]
cat test.cpp
struct Vector {
Vector() : x(0), y(0), z(0) { }
float x,y,z;
};
struct Foo {
int dummy; // commenting this out makes it run perfectly
Vector array_of_vectors[4];
};
Foo foo;
int main() { }
11:14:35 [~/idownload]
g++ -O3 test.cpp -o test
11:14:54 [~/idownload]
./test
