fyi, this seems to be fixed on trunk 20190701

Well, I can't reproduce that. 

For me the failure still triggers with current trunk:
...
$ ./dwz multidictionary 
dwz: /data/dwz/dwz.git/dwz.c:9108: write_die: Assertion `refd != NULL' failed.
Aborted (core dumped)
$ ./dwz -l0 multidictionary 
Segmentation fault (core dumped)
...

FTR, this is a pragmatic fix. For something more structural, I've filed PR25229
- "Add input verification phase".
