Description: The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage
void SkyQPainter::drawSkyPolyline(LineList* list, SkipList* skipList, LineListLabel* label)
SkyList *points = list->points();
bool isVisible, isVisibleLast;
// & with the result of checkVisibility to clip away things below horizon
isVisibleLast &= m_proj->checkVisibility( points->first() ); <--- BUG

Ordered visibility check for first point of SkyPolyLine in drawSkyPolyline function
Variable isVisibleLast and isVisible are not initialized so stores random value while operated and with check visibility and correct visibility of point are stored in same variable when passed to toScreen function.
