I have a class member (boost::shared_ptr):

class XYZ
{
private:
boost::shared_ptr<int> m_pBuff;
// other member
...
public:
void func(int n)
{
m_pBuff.reset(new int[n]); // or m_pBuff =
boost::shared_ptr<int>(new int[n])
...;
}
// other functions
...
}

The func(n) will be called many times inside / outside the class. Can I use
shared_ptr here like:
m_pBuff.reset(new int[n]);
or
m_pBuff = boost::shared_ptr<int>(new int[n]);

I tried both and get error said heap corruption

The error is passing an array to a shared_ptr. Take a look at shared_array ;-)

HTH, Kris
