On Linux, Dr. Memory will look in the default debug directories for symbols for a library: a .debug subdirectory of the library's directory or in /usr/lib/debug.

On Mac, Dr. Memory will look in the default debug directories for symbols for a library: a .dSYM subdirectory of the library's directory.

On Windows, the _NT_SYMBOL_PATH environment variable is honored by Dr. Memory as a local cache of pdb files. However, Dr. Memory does not support symbol store paths (those that contain srv).
