QVector of structures without default constructor

[AD]

Hello. I have stucture without default constructor.

struct LOGRECORD
{/*.....................*/};
 
class M
{
QVector<LOGRECORD> log;
 
M();
/*.....................*/
};
 
M::M(): log(0, LOGRECORD(/*parameters*/))
{}

struct LOGRECORD
{/*.....................*/};

class M
{
QVector<LOGRECORD> log;

M();
/*.....................*/
};

M::M(): log(0, LOGRECORD(/*parameters*/))
{}

But compiler had next errors:
