compile .cpp.elf section '.bss' is not within region 'ram'

Hello,
I am redoing my code on a Due which used to compile and run and I get the error:

c:/program files (x86)/arduino/hardware/tools/gcc-arm-none-eabi-4.8.3-2014q1/bin/../lib/gcc/arm-none-eabi/4.8.3/../../../../arm-none-eabi/bin/ld.exe: 
address 0x20088080 of 
C:\Users\MYUSERNAME\AppData\Local\Temp\build2309789141682166882.tmp/MYPROGRAM.cpp.elf 
section `.bss' is not within region `ram'

When I go to C:\users\MYUSERNAME\AppData\Local\Temp\build2309789141682166882.tmp, I don't see any file ending with .elf

This problem is happening because I am redoing code inside:

template<typename Data>
/**
@brief
*/
class Vector {
    public:
        size_t d_size; //  Quantity  of stored objects
        size_t d_capacity; //  allocated capacity (here, it is forced to 10.)
        Data d_data[10]; //   storage
 

    
    public:
        // Default constructor
        Vector()  { 
            d_size=0;
            d_capacity=10;
        }; 
 //,,, more code...
}

The change is to get rid of all new and delete commands and just put a fixed array. I get the compile error 3 times, just id doesn't say where in the source file there's a problem. How can I get that?

Exactly what does the error mean? Is it running out of RAM?

I will also see if it is feasible to not redo the whole class and see where it stops being compile-able.
Advice please,
Thanks,
Frank

Last time I had this error , I assign an array too big in size. You are out of RAM.

It worked. I examined the temporary directory of the previous build. Inside the .map file, I checked the memory usage. I trimmed off the big parts.
Thanks,

Also its usually the correct option when one class contains a reference to another
class to use an explicit reference or pointer, not include an instance directly in the class's data members.

An array of pointers uses less RAM and permits members of the array to be null and
unused and take up no extra space.

Perhaps I was wrong to assume this of your "Data d_data[10];" declaration, but you
have only provided a snippet.
