GCC doesn't produce "unused variable" warnings for 'vec' and 'str' in
the code below:
#include <vector>
#include <string>
int main()
{
std::vector<char> vec;
std::string str;
char c;
}
When compiling this with either GCC 4.6.3 or 4.7.2, I only get:
$ g++ -Wall -W main.cpp
main.cpp: In function 'int main()':
main.cpp:8:14: warning: unused variable 'c' [-Wunused-variable]
It catches 'c' as being unused, but not 'vec' and 'str'. Is this on
purpose, or did I run across a bug?
