Comment(by strk):

 Sounds useful:
 NOTICE:  [gserialized_gist_nd.c:gidx_copy:89] copying gidx
 (0x7f8d276adfa0) of size 964952070 to gidx (0x7f8cec988048)

 Aren't we returning memory allocated in a local variable, btw ???!!!

 {{{
         char gidxmem[GIDX_MAX_SIZE];
         GIDX *bbox_out = (GIDX*)gidxmem;
 }}}

 You can't safely return bbox_out then
