 not sure if this is a defect, but the assertion in gc.c on line 107 fails
 when passing in size 0. i realize it sounds a little dubious to try to
 allocate 0 bytes but several popular gems will try. mysql and mysqlplus
 both attempt to allocate 0 bytes when querying an empty table containing
 varchar (or blobs, or similar) from a prepared statement. rubyzip does
 this as well when decompressing a file that does not contain a comment in
 the zipheader. i patched the gems to work with macruby 0.12 but i suspect
 the assertion is non-standard. i haven't tried to verify these cases with
 ruby 1.9.3, but it seems likely that ruby_xmalloc_memory should probably
 return NULL when attempting to allocate 0 bytes.
