Iray crashes, taking DS with it in certain scenes.

Penguinisto

I know I'm normally quiet and have been for what, decades now? 

However...

Upgraded DS, and built a new character just for fun - then I run a render to see how things perform.

Tried to render it, and DS crashes. 

Figured maybe something I used isn't compatible, so I tried again, this time with a whole new pile of stuff...

DS crashes again.

I check the logs, and (rant mode:) maybe someone can explain what the hell this is?

(Seriously, this is a MASSIVE red flag, guys... I daresay this could be a potential security hole to boot, but I hadn't bothered to look into that just yet.)

Edit/Update: it was the stupid Transmitted Hair thing that others have pointed out....

But that filepath thing still bugs the crap out of me. No, really, it's pure cringe...

It is the relative path to the source code for the module that gave issues, with the line number - it is logged for the developers should they need to investigate the issue (which is not the case here, since it is a known issue with a known workaround/fix).

(heh - I know what it is... but... I'll leave the topic be. It's still cringe to see it, though. :/ )
