segmentation-fault .. AnsiStringToUnicodeString as first debug-error-line .. doobious class-hieracy - c++

Question

I tried to make the classes hold RAII standards (as I get it .. I'm a hobby programmer), but the compiler/debugger complained about missing constructors (with empty brackets), so I added them + set_value() functions.
The point of elaborating so much on a simple rectangle is to lift the cloudiness of integrating GUI-types (top-down types like buttons and text-fields) from the foreground problem I'm trying to handle: openGL 2D & 3d graphics living in a lower-left coordinatesystem.
enum class eAnker:int{
high_left,
high_right,
low_left,
low_right,
}
class anker
{
friend node_handler;
public:
anker(){};
anker(glm::dvec2 Vec2):pPoint( new glm::dvec2(Vec2) ){};
anker(glm::dvec2 Vec2, eAnker ea):pPoint( new glm::dvec2(Vec2) ),anker_type(ea){};
virtual ~anker(){ delete pPoint; };
void set_value(glm::dvec2){pPoint=new glm::dvec2(v);}
void set_anchor_type( eAnker ea){ anker_type=ea; }
bool operator<( anker& a ){ return (pPoint->x<a.pPoint->x)<(pPoint->y<a.pPoint->y); };
protected:
glm::dvec2* pPoint;
eAnker anker_type;
};
class nRect:public anker
{
friend node_handler;
public:
nRect(){};
nRect(glm::dvec2 p):anker(p){};
nRect(glm::dvec2 p,double lineHeight, double letterWidth):anker(p),plHeight( new double(lineHeight)), plWidth( new double(letterWidth) ){};
virtual ~nRect(){
delete plHeight;
delete plWidth;
};
void set_dims( double Ww, double Lh ){
plWidth= new double(Ww*LETTER_PIXEL_WIDTH);

//no errors so far. when leaving split_current(..), the execution halts with a SIGSEGV

link is a follow-up, on the same code, that probably contain the proper answer to the erratic behavior described. In short (as I understand it): classes with pointer-members needs customized copy/assignment operators these they are at work, without your notice, behind the code you write .. the default ones won't work.
I didn't provide them.
