+exploring the millions of star systems.  Turn to a life of crime as a pirate,
+smuggler or bounty hunter.  Forge and break alliances with the various
+factions fighting for power, freedom or self-determination.  The universe is

-the dict -> StableDict change is just for being more specific,

-Subject: [PATCH] Add bound checking to all srfi-4 vector allocations.
-
-Do what C_allocate_vector already does and prevent the creation of a
-vector that's too big or too small.
-We should be very careful to avoid the latter case because the
-allocation size is directly fed into `malloc' as 'x + sizeof(C_header)'
-thus making possible to successfully allocate a vector smaller than the
-C_header structure and get C_block_header_init to write over
-uninitialized memory.
-
-To reduce code duplication, type checking is moved from each of the
-make-*vector procedures to the common "alloc" helper procedure.
