Package: g++-3.3
Version: 1:3.3.2-0pre4
Severity: normal
The output of the following code, when compiled with g++-3.3 is '2'. It
should be '1'.
#include <iostream>
struct foo {
foo() : v(0), c(0) {}
int& value() { c++; return v; }
int count() { return c; }
int v, c;
};
int main(int argc, char* argv[])
{
foo f;
f.value() = (argc - 1) ? 0 : 1;
std::cout << f.count() << std::endl;
return 0;
}
f.value() is evaluated twice for the ?: operator.
