Summary0009542: Crash when trying to render Titan Fat
DescriptionIn this http://dffd.bay12games.com/file.php?id=11752 [^] save I had just killed an unwelcome visitor (Mountain Titan).
One of the dwarfs was kind enough to drag the carcass to the butcher's and cut it up.
One of the resulting materials was Mountain titan fat x77 which I was hoping would feed my soap need.
The item is currently forbidden in the butcher's.
If enabled a dwarf will try to render it to tallow which will cause the crash.

If you press Z -> Kitchen -> Meat .. you should find Mountain titan meat but no Mountain titan fat which I thought was odd which is what leads me to believe that this is the problematic item.

If I understand the DF fault finding process correctly, you should first disable DFHack and load your save without it, unforbid the fat, and then resume. If it still crashes it's less likely to be caused by DFHack, with the DFHack error report just being a detection of a problem rather than a cause.
After that test I'd add a note with the results.

If you check your stocks screen, you'll see the fat. Fat doesn't show in the kitchen menu. Once it is rendered, the tallow will show.

Check with DFhack forums for this bug. The fat was rendered fine and there was no crash when I used vanilla DF 42.05.
