While playing around with Debug.locate_references i noticed that it fails on ({}). The problem seems to be that in print_short_svalue_compact the svalue is not completely initialized and at some later point s->subtype is added to a pointer. 1-line patch attached.

There is another problem when the master is printed during a run of locate_references. As the one before it can be triggered by Debug.locate_references(({})) but only after fixing the first bug. The current_path variable inherited from the 7.4 compat master is type PIKE_T_FREE for some reason and describe_svalue doesnt like that. If pike is compiled with dmalloc, pike segfaults because the free location of current_path seems to be uninitialized, too. Not sure where to fix that.
