No.

No, you are freeing the memory allocated in g_strdup. g_strstrip does
not allocate memory.

#define g_strstrip( string )    g_strchomp (g_strchug (string))

Both g_strchung and g_strchomp works with the string you passed to it
and does not allocate memory.

The first moves the text to the start of the buffer with g_memmove and
the second just places a null character in each space character from the
end of the buffer to the first non-space character.
