+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.
