Segmentation Fault (core dumped)

[ADTR2012]

When I compile my program using my Makefile I get a segmentation fault. I checked through my code and it looks correct so maybe it's something else I did wrong? My error message is this:

-bash-4.1$ make tests
./test_default_ctor
Done testing default constructor.
./test_c_str_ctor
Done testing constructors.
./test_add
make: *** [tests] Segmentation fault (core dumped)

What does this mean? I am very new to Unix.

It means your program test_add is crashing.
