uClibc++ memleak

[Thomas Volpini]

Hello,

I've found a memleak in uClibc++'s vector, you can find a test program and the
fix below. I'm not sure if there are similar issues in other classes.

Regards,
Thomas



#include <vector>

struct foo {
  std::vector<int> bar;

  ~foo() {
    printf("dtor\n");
  }
};

int main() {

  std::vector<struct foo> v1;

  foo f1;
  f1.bar.push_back(1);

  v1.push_back(f1);
  v1.push_back(f1);
  v1.push_back(f1);

  v1.clear();

  return 0;
}
