Sorry, by empty I mean that there's no IR. That is:

   % opt -S -o - clusterfuzz-testcase-minimized-5935702182199296.dms
   ; ModuleID = 'clusterfuzz-testcase-minimized-5935702182199296.dms'
   source_filename = "clusterfuzz-testcase-minimized-5935702182199296.dms"

I think 12 bytes is approximately the smallest valid bitcode file.

In any case, this doesn't seem to reproduce with current ToT, and I see  
that it happened while we were changing how llvm's OSS Fuzz flags worked. I  
suspect this was a transient issue.
