Adds code that supports source-file:line-number lookup. This will load debugging symbols at the start of a program allowing one to print source file / line number information.
Turning this on causes libcwd to print source file and line number information about where memory was allocated in the memory allocation overview. It also provides an interface, allowing applications that link with libcwd to print debugging information using the symbol table.
As a developer, especially when you are debugging memory allocations.
This is enabled by default. Use configure –disable-location to disable it.
