Subject: [PATCH] corba-loc: Do not allocate more tokens than necessary.

To split the list of locations, the code calls g_strsplit with the
last argument set to G_MAXINT.  It means that g_strsplit will try to
allocate a huge array (G_MAXINT + 1, for the final NULL), mostly
filled with NULL.  Unfortunately, on 32-bit systems, this is one past
the authorized length for an array.  Previous versions of glib would
not care, but the new version now raises an error if this happens.

To get an array of the appropriate size, we can just pass -1 to the
last argument.

* src/orb/orb-core/corba-loc.c (ORBit_corbaloc_parse): Replace
G_MAXINT with -1.
