Re: Help with strange (for me) STL problem that disappers when rebuilding all

I have a class Bounds with two constructors:

class Bounds
{
private:

        list<Segment> upperLinearSpline; // Upper bound.
        list<Segment> lowerLinearSpline; // Lower bound.
...
}

Bounds::Bounds()
{
}

Bounds::Bounds(double lo, double up)
{
        lowerLinearSpline.push_back( Segment(Point(0, lo), 0, -HUGE_VAL,
HUGE_VAL) );

        upperLinearSpline.push_back( Segment(Point(0, up), 0, -HUGE_VAL,
HUGE_VAL) );
}

Segment is another class with default constructor.
I have not defined destructors, copy constructor and copy assignement.
So the automatic membewise-copy should be used.

The class Bounds appears in other classes in the construtors as or/and
as reference member data like
....
private:
    const Bounds& bounds;
...

Until here everything is working fine.

Now I write code for another class in which Bounds appears only in the
constructor as (not as member data) like:
UniformEnvelope::UniformEnvelope(const Bounds& bounds, .......

and what happends is that when I add the source code and header file
of this new class and compile normally the constructor
Bounds::Bounds(double lo, double up) stop working.
In debug mode I get no error/exceptio at all but I notice that the
push_back() is not working correctly. It does not report any error but
if simply fails to insert the value.
