Ebben hol van a hiba, miért ír ki rá heap errort? a classban ezek vannak: void* mem; unsigned int size;

void main(){

ktMemAllocator *t=new ktMemAllocator;//ebben csak "reset" van

t->putData("test");

t->free();//a hiba ebben van

_CrtDumpMemoryLeaks();}

void ktMemAllocator::create(unsigned int _size) {

mem=new char[(size=_size)];

clear();

}

void ktMemAllocator::clear() {

if(mem)

memset(mem,0,size);

}

void ktMemAllocator::putData(const void* _dat) {

if(size==0){

create(strlen( (char*)_dat));

}

if(strlen((char*)_dat)<=size){

strcpy((char*)mem,(char*)_dat);

}

else{

MessageBox(0,"mem error","error",0);

}

}

void ktMemAllocator::free() {

delete []mem;

}
