We are building a large application with gcc-3.2.3 and when we use the
-O3 flag with our g++ instance it causes the runtime app to seg fault.
If we use -O0 then it works just fine. This applies to code built on the
x86_64 platform. If it is built on an X86 platform and run on the x86_64
then it is fine.
Anyone have any ideas?
Here is a piece of code to replicate it:
/* test.cpp */
#include <iostream>
using namespace std;
void test1(...) {
}
void test2(int i, ...) {
}
int main(int, char **)
{
cout << "Testing 1..." << endl;
test1(1, 1.2);
cout << "Testing 1 OK" << endl;
cout << "Testing 2..." << endl;
test2(1, 1.2);
cout << "Testing 2 OK" << endl;
return 1;
}
/** END ***********************/
Use g++ -m64 -O3 testmain.cpp
Then run a.out
