Is it possible that you have non-determinism in your harness? That could cause different outputs for minimization...

So maybe I misused it? I pointed it at a directory (I think pointing it at a file failed, but I'll have to recheck) containing several dict files (gif.dict, jpeg.dict,...

Can you show the command line you used? Are you using the latest versions of everything (DynamoRIO, winafl)? What OS? Does running it without drrun.exe work, or also crash? Does...

I meant you should try running it directly without drrun OR winafl, i.e.: `C:\Storage\WinAFL\POC> WinAFL_POC.exe "Files\id_000082,src_000000,op_flip1,pos_179,+cov.jpg"`. Does that work fine? crash? You can also try `echo %errorlevel%` to see if...

So this works without crash/error/failure/event log? `C:\Storage\WinAFL\POC> WinAFL_POC.exe "Files\id_000082,src_000000,op_flip1,pos_179,+cov.jpg"` And what about this: `C:\Storage\WinAFL\POC> ..\DynamoRIO\bin64\drrun.exe -- WinAFL_POC.exe "Files\id_000082,src_000000,op_flip1,pos_179,+cov.jpg"`? And the original command line shows the exact same error? Or did...

Since `..\DynamoRIO\bin64\drrun.exe -- WinAFL_POC.exe` doesn't work, unless you managed to fix it with the answer you found, I would advise to ask in DynamoRIO repo, because it seems the problem...

I can confirm that this change fixes issue https://github.com/marcgibbons/django-rest-swagger/issues/815 on my machine

This sounds like a pretty good solution to me. I would probably backtrack to the beginning of the current basic block (whether it's short or long, to avoid problems with...
